Due to colder weather brought in by some very much needed thunderstorms added with a break in the rain I figured I'd take a trip out to the local track to test out my newly added mods and hopefully better my times.
So off to the track we went with a half tank of 87 octane petrol, an SCT3 tuner and a video camera in hand.
After arriving at the track and teching in, I went straight to the almost empty staging lanes with a fully warmed and very heatsoaked car. Within no more than 1 minute I was already being flagged to the line against another s197 Mustang. I had a chance to talk to the other driver while we were waiting in the staging lines from our rolled down windows. He asked me what I had done so I told him I had a catless h pipe and a cai/tune. He responded with a very smug tone "Twin turbos!" So I figured I'd get blown away, which would be pretty cool.
After our little conversation we got lined up and waited for the ambers to flash. I held my revs at about 2000 rpms and as the last amber flashed I did my usual clutch dump, but instead of a little tire spin and hooking, it bogged which caused the front to dip harshly and the rpms to drop off to about 1200. So I held my foot full down on the throttle to power out of the bog, but the rpms seemed to take forever to pick back up and the car just didn't seem very responsive. But then again, niether did the twin turbo car, because it was pulling away at a very slow rate and then he must have missed a gear because I rocketed passed him to a very uneventful 15.044 @ 98.69 mph.
The 60' time for my first run was also a dismal 2.560.
At this point the night didn't seem to be going very well since I've never run anything over a 14.8 even on my most botched runs.
Since the track was very empty lastnight I was able to line up again and make another pass within 5 minutes and netted another low 15 second pass with about the same mph and same 60' times. I soon realized the car was bogging and stuttering with every shift down the track, which I knew was killing my times, but I couldn't figure out why it was running like this. I had noticed this for the last week or so driving around town, but it wasn't as apparent because I wasn't concentrating on what the car was doing very hard. I made a couple more passes and recieved the same results as the first two, which was very frustrating.
I figured the very humid 90 degree heat, added with a lot of heatsoak could have been the culprit of the extreme bogging so I parked it and lifted the hood to give the car a 30 minute cool down. Which worked out nicely because right after I parked my car a driver with a very modded chevy II popped his chute by accident just after leaving the line and dragged the chute to the end of the track. Then a car leaked oil down the track, this caused the track to shut down for about 45 minutes, which was a perfect cool down opportunity. At this point I was talking to my g/f about the car and how it didn't feel like it was responding like it should be and we both agreed that the weather might be the problem, but the 15 second passes seemed way too high. So I told her that if the cooldown didnt fix the issue then I was going to go back to the stock factory tune instead of the custom 87 tune I was using. She agreed this was a good idea.
After the cool down I lined up in the staging lanes again and waited my turn, but this time pushing the car with the engine off untill the last moment when I got flagged to make a run. Unfortunately this cool down didn't help at all and I made another 15 second pass with all the same issues I had on my previous runs. Just to back it up, I made one more pass with the same result.
Very irritated at this point I pulled over and got out the tuner to upload the factory tune. I was a little skeptical that this would help, but I was out of options.
Now with my factory tune installed I lined up to take another go. This time When I launched there was no stumble and no nose dive, just grip and smooth, hard excelleration along with perfect shifts. I clicked off a 14.215 @ 100.63 mph with a 2.2 60'. I was elated and very confused at the same time. Why would my factory tune work better than a custom tune that has netted people with the same mods as mine low 13 second runs? My next 3 runs were all 14.2 runs as well and my last run of the night was a 14.3 @ 102 mph, tieing my best mph that I made last winter in 50 degree temps.
Overall I was satisfied with my trip to the track lastnight because I beat my best time ever by a tenth of a second and the air temps lastnight were 40 degrees higher than my previous best pass. I'm sure had it been better temps I would dipped into the 13's lastnight.
Needless to say I'll be calling my tuning company on Monday to have a chat with them about what's going on with thier software.
BTW...That twin turbo mustang I mentioned never broke out of the 15's lastnight...ouch.
Ask for a new tune, same kind, just a new file. Tell them what happened. Wipe out your tuner, all the cal files so they can't "cross talk" on accident. Make sure you are back to stock before you clean the tuner out.
Seems something got lost in the cal file, isn't to uncommon.
Sometimes we get cals e-mailed from the UK or Germany at work and they need to be resent because when the file is taken apart and put back together over the WWW, appearently it doesn't always go back together the same way?
They'll take care of you, that's a good outfit.

Given them a call...Have you tried the 93 tune at the track?
The best I can get in AZ is 91, so thats the max tune I got from them, but no, I havent tried the 91 tune yet. Last night was the first time ive been to the track with the cai/tune.
When I installed the kit, it felt more lively and more snappy, but I never did feel that huge kick in the pants that everyone always talks about. It certainly didnt feel like it gained 20+ whp like everyone states. Don't most cars et at like 13.8 or better at 103 or faster with just a cai and tune from brenspeed or bama?
I agree, get a new tune installed.That car should be running 13's all day HOT OR COLD.
That's what I figured. Heck, I should be able to get this thing into the 13's bone stock. But even with a 2.1 60' and a 102 mph trap the best I could manage was a 14.3.
There are guys on here that have run lower traps speeds and got worse 60 foot times that have hit 13's...I dont understand how that works out. But I figured after the o/r h pipe and just the 87 tune I'd be good for 13.8's at the very worst.

The heat and humidity here are affecting these cars.The tune maybe as well.

You really need to run the 91 or 93 octane tune. They can adjust the timing with the higher octane and that's where you'll feel the power difference.
