I own a Torch Red 2005 GT which was the first one sold in Arizona. December of 2004. It is a blast to drive and has given me no problems worth mentioning.
I have a question about my Saleen Series IV Supercharger, installed by Jim Click Ford in Tucson. (Great work!)
Here are some of the mods I have done so far. which might affect any answer to my question. Steeda CAI, Bassani Cat Back Exhaust, Ford 39# Injectors, ZEX Dual Bottle Nitrous System, Autolihe NT0 spark plugs, removal of hydrocarbon trap.
After having the Saleen SC installed I continue to get a DTC light which, when I check it with my Predator, shows a lean bank. I reset the alarm and it comes back within a few miles.
When the Saleen SC was installed the computer was sent to Saleen for a custom tune. I spoke with Saleen Tech Support and was told the Predator can not change the Saleen installed tune. The support ech suggested I flash it back to stock and then 'mess with it'.
My question is, has anyone with a Saleen Series IV SC tried to or actually used a Predator to modify the Saleen tune, or, as suggested, flashed it back to stock.
The car run very strong. I don't want to lose how well it runs just to get rid of a DTC alarm nor do I want to run it so lean as to damage the engine.
As long as the stock ECU was flashed by Saleen and no aftermarket chip was put in AND the predator is for that car then yes, you should be able to do what you need with the predator.

That kind of what I thought too. I have the factory tune in the car so woesr case is I go back to stock. Saleen wouldn't tell me what the did to create the tune, i.e., parameters, so I'll see if I can raed their tune and grab the changes.
Very interesting thread. I am actually taking mine in for a custom tune/dyno all day tomorrow. Larry Roesch Ford in Elk Grove, Illinois installed the Saleen SC and the Check Engine light is always on. I took it back to them and when they spoke with Saleen directly they blamed it on the CAI but said they would have to reflash there computer in order to get rid of it. That was fine with me, but then come to find out that the reflash will void the warranty??? I know I will probably need new injectors after the tune, but do you think this will get rid of the check engine light?
.... I am also a novice, anything else you more experienced guys would have me check on when the tune is finished?? Thanks for the help in advance. I don't want to go BOOOOOOOOOOOOOOOOOOOOM
I wasn't told anything by Saleen about the warranty being voided, it was just that the tech didn't want to or couldn't answer my questions. All Saleen did was load their own tune. So, If I can figure what their tune does, I should be able to replicate it. I guess it's one of those 'magic' things the manufacturer wants to keep close to their chest.
In any event, I don't want to go back to the stock intake and filter as was the suggestion by Saleen. All I need to do is enrich the mixture, which I was able to do with the tunes provided when I bought the Predator.
I'll play with the tunes this weekend and report back how the car responds.
BUT, had I know this would be a problem (the check engine light on all the time), I may NOT have purchased the Saleen SC. Hey Saleen, you READING THIS.
If I was considering a Saleen, knowing what I know today, I would certainly ask some detailed questions of Saleen about how to modify their tune before I shelled out 6 grand for the product and installation.
Bankrtoy - forgot to answer your question about new injectors. I installed Ford 39 # injectors. I do 'feel' a top end performance increase. The engine no longer feels like it is running out of fuel at wide open throttle and high RPM's. However, the larger injectors did nothing to eliminate the check engine light coming on all the time. I am still getting the name code "Lean Bank".
HMMMM... Sounds like we have similar problems due to the intake. I was hoping the injectors would help solve the problem.. I am taking her in tomorrow for a prof. tune so we'll see what happens. BTW, where did you get your 39lber from? I've been looking without a whole lot of luck. I also paid 6k for the SC and install. I love the feel and the power, but the sound is what really gets me What kind of #'s did you get on the dyno?
I have not had the car on the dyno yet. It a 'gotta get to it thing'. I bought the 39# injectors, brand new off eBAY. You can look up the auction 8039241143 and get the details and seller to see if he has anymore. It took me about 30 minutes to put them on. I changed to Autolite HT0 sparkplugs at the same time - also purchased new off eBAY.
Let me know how your tune goes and/if you are able to work out the lean problem. It may be a fix for all of us with Saleen SC's.
As for performance, I agree with your assesment. It is great. Acceleration is fast and smooth. I enjoy the supercharger 'whine'. Those in the know who hear it understand what is under the hood. Except for the persistent lean problem, I am happy with the equipment and the price I paid.
Dude, getting that car tuned is a life and death deal for your motor with a blower on it. DO IT SOON!!! Take time off work if you must, but it's gotta get done.

went in for the tune yesterday. BIG PROBLEM! I have the Diablo and apparently the Diablo can't overide the tune that Saleen loads. The car has to go back to the Ford dealer to be reflashed to the stock tune, then and only then will the Diablo be able to change the tune. Does this make sense? Even if I am only driving a few miles can the stock tune hurt the motor during that drive? HELP please
Update on the Saleen SC lean problem with my CAI. I realized this afternoon that I had not reset the check engine light (cleared the trouble codes) since I installed the 39# injectors. I got so used to seeing the check engine light on I have simply been ignoring it.
Today I used my Predator and reset the trouble code. Of course, as usual it was the 'Lean Bank 1' code. I drove the car for about 50 miles after resetting the code. Some driving was just puttering around in traffic and a few wide open shots on the Interstate. SO FAR, no check engine light.
Before the 39# injectors I would get the LEAN trouble code in the first couple of miles of driving. Now, nothing. I am not totally sure if the fix should be attributed to the 39# injectors but so far it seems installing the new injectors has worked.

You light is coming on because of your fried 02 sensors.......You really all need a chip and tune. .....Getting a custom chip solves so many problems.......I manage to pass inspection with flying colors in a 600 hp Gas guzzler All modded.........All because we "turned off" all the Bad codes (the CHk eng, and Low water, etc...) and they stay off.......
I am always surprised to see guys go to bigger injectors without first determining if they are needed. During our tuning sessions we look at MAF counts and injector duty cycles. Most of the time, unless some really radical changes have been made, injectors are not needed.
Saleen SC IV Tuning Question 
What kind of #'s did you get on the dyno?
