I finished the install this morning, taking my time installing the Boost-a-pump. I jacked it back up and removed the driver wheel and the fender well and ran the wiring through to the engine bay there. I also got my AF sensor wires in from there and then buttoned it all back up.
Before going further, I spent some time cleaning up the wiring further, rerouting the fuel line, and using lots of zip ties to straighten up the wiring as good as possible. Once I was satisfied, I got the battery in, filled the intercooler and engine with coolant, and proceeded to upload the tune.
Programming went off without a hitch, and I started it up. No leaks that I can find, and it ran smooth as silk. I warmed the engine up and topped off coolant after thermostat was open, and checked everything one last time.
I took it for the mild drive, and it idled perfectly and ran smooth out of boost. The last stretch before home I jumped about 3/4 throttle and got into a little boost. I don't have a boost gauge yet, or a fuel pressure gauge, and at the time the AF wasn't hooked up, but with everything going perfect so far, the last step in the manual was to enjoy the new supercharger. Seemed to pull well, sounded awesome, but I was so jacked on adrenaline from worry/excitement, I don't know how it was feeling really..
I got it back in the garage (3 minute drive was all), and wired the AF gauge in. I don't have a pod yet but I wanted to make sure I had proper AF ratio before driving it any more.
Took me a while to find an accessory line to connect to, and finally I had it plugged in. I fired it up and at idle I had about 13.5:1 af ratio, dropping to 11 when I goosed the pedal a little. So I took it out on the street for the 3 minute run again. At idle all of a sudden it was running 15.5-16:1, about 15 at mid throttle, and when I finally got out on the road I hit WOT up to about 4500 rpm and it never dropped below 14.5! I wasn't sure it was just lag since I was only on WOT for like 2 seconds, so I tried again and sure enough it never got below 14.5 (drops to 10 and then goes blank when I got off the throttle, so I had to be sure). As I pulled it into the garage it was still idling perfectly.
I checked all my connections to make sure they were right, checked for vacuum leaks and couldn't find anything obvious, so I busted out my SCT x3 to see if I could do some data logging. I let the engine cool for like an hour while I loaded software on my laptop, and when I finally went back out to plug in and monitor stuff, it was idling pretty rough.
I pulled a few plugs to see if anything was melted from my WOT tests, and they look fine, so hopefully I didn't cook a cylinder.
I have a feeling that they sent the wrong tune because I specified the canister filter and they sent the square filter that uses the factory MAF housing. I am thinking that when they programmed they programmed for the larger MAF housing and canister filter and that is throwing the whole thing off. So now I have to get in touch with them tomorrow and see if I can next day the tuner to them and get them to check it.
There is one part left over that is not found anywhere in the manual or supplements.. its a ring that looks like part of an intake.. about 4" in diameter and curved in like a transition from one size to another. It has a flat side on part of the outside of the ring. I went through everything like 3 times looking for it and it isn't even in the parts list pictures.
Anyway, the car is parked until I can talk to them and see what they think. Kind of a bummer, it is a nice day and I would love to be out cruising and at least breaking in the gears that I put in a week ago...

Wow you need to have that dyno tuned. Its running lean. Where is the AF O2 sensor mounted?
The bung is directly after the drivers side cat. I am convinced at this point that it is one of two things - either there is a big vacuum leak under the supercharger, or the tune is WAY off because of the filter screw-up. Now that it is idling rough, I see it as possibly the vacuum leak, so tonight I might pull the supercharger and check the gasket to make sure it didn't roll out of the channel when I placed it. Shouldn't take me more than an hour to do that. Depends on what KB says today.
Funny thing.. KB is adamant about the whole dyno tune thing. They have pages of what could be considered a rant about how they have spent thousands of hours dyno tuning mustangs with a $225,000 dynojet dyno. They basically insist that most dyno tuners are amateurs that are just looking to make a buck by getting a few more HP out of your supercharger by running a little more advance.. Personally, once you read through what they have to say about it, it makes good sense. There is a place for dyno tunes with superchargers, but a totally stock engine with just one power adder should have no problems at all running on the manufacturers tune, unless you are interested in taking a risk by adding more advance or leaning it out a little.
It is a moot point anyway because there is only 2 dyno's in town and both places don't have any expertise with mustangs.

They seem to think that A) the sensor needs to be mounted before the cats, and B) that almost all AF gauges can be off by +/- 1.5:1, so I might read up to 13:1 or as low as 10:1 and still be at 11.5:1. I don't think I quite buy it, but I'm not a professional..
The extra part I had needs to be glued into the factory air box, which *MIGHT* account for a little of the problem too. Also, I am going to pull the supercharger off to make sure the o-ring didn't roll out of the channel when I installed it.. a vacuum leak might account for the rough idle now.
Still waiting to hear back on the tune, if they sent me the wrong one as well..

Stl is right. I would still put it on a dyno to see what's going on with it after you check the O ring.
Yeah, I'll move the bung, but on a dyno, they measure at the tailpipe!? How is that different than after the cat, and any different than the reading I get with the AEM gauge?
Also, when the cat is totally cold, it should read the same as before the cat, since it can't catalyze unless it's hot, but I still read 14.5 at idle when totally cold.
BTW, I went home at lunch and started it up, and it idled perfectly. But then I let it run for a bit, then let it sit, then started it and it idles a little rough. It's like it misses occasionally at idle. I have not thrown a single code yet though.
Still waiting for word on the tune.

OK, KB hooked me up and I am sending the tuner back red label, and tomorrow they will re-program it and send it along with the canister filter and 90mm maf housing 2 day air, so I will have it before the weekend. I will get the bung moved so it's before the cat, and now I just have to get a gauge pod and the boost and fuel pressure gauges coming.
Now I can sleep tonight.. hopefully.

Measuring at the tailpipe is much less accurate than before the cats.
So KB checked, and sure enough they sent the tune for the cannister air filter, but sent the california emissions filter setup, so that explains the lean condition. I already took the bumper back off and removed the airbox and stuff, and it's ready for the new parts when they arrive. Should be here Friday, or hopefully Thursday if I'm lucky.
Also, they don't think I could have hurt the engine, because their tune programs so when the knock sensors detect a ping it retards the timing up to 20 degrees, so if I was pinging with my 14.5 af ratio, it would have backed the timing way down. If it was pinging on my WOT tests, I couldn't hear it. It definately didn't sound right though (although the supercharger sounded friggin awesome!)
The tuner tech said they haven't seen a 3v 4.6 blow with their stage 1 or 2 kit since the early days when they first came out.
I'm not exactly happy that this happened, but I am happy that I was right in my diagnosis, and that they are correcting the problem asap. Excited again to get this running right.

Very impressive job! This is definitely not something I would want to tackle in my garage. Hopefully the new KB tune will get you back on the road and hammering down on the asphalt! If you do dyno it, post you numbers or even better your graph

Thanks! I am really itching to get the filter and maf housing in so I can go for a drive.. I am hoping it shows up tomorrow..
There isn't much for dynos around here, and this tapped me out big time.. I can't even afford a boost gauge right now.. But perhaps later in the summer I will go and have it dyno'd - after I recover financially, and after I redo the kitchen before the wife kills me..

Wow glad you figured everything out!! ive been reading this post since you started it. its like a novel with ups and downs and plot twists. And hopefully by Sunday a Happy Ending! Also my blown car idles at 14.7. But it richens up very quickly when you hit the gas. I give you props for installing it yourself.
