your tips on the exhaust leak was right on...found a leak on the side opposite of where I thought the problem was, re-positioned the clamp on the CAT to the header and FT's straightened right out. O2's at WOT are dead even....thanks man and keep up the good work!!

all very good info monte....i am off to check all you have suggested....i will let you know the results of ny findings.

monte.....good tips on checkout...however, shouldn't only leaks prior to the numbe1 O2's be of concern? I have the rear O2's P codes deleted.....or is a leak past the number 1 O2 still going to be a problem??

with only one side being that far off, and you said you already replace the O2, I'd check for a leak somewhere in the piping. since you say you had taken it apart to bust out the CAT, could, could very well be a leak somewhere now, or even a hole in the CAT itself now.

I have a 1999 SS Camero LS1 and a u7198 predator. When I bought the predator I sent you my stock tune after I added these bolt ons....SLP CAI, SLP LID, SLP LT headers, SLP Loudmouth exhaust with high flow CAT's, and AIR removed. You then sent me a custom tune wihich I installed and seemed to work ...

You should have a copy of it saved to your computer from when you first loaded it.

Thanks

yep I have a copy...thanks!!

I have a custom tune for my 1999 SS that you sent me a while back. It is installed in my car right now. If I were to re-install the factory tune will the custom tune stay in my predator or will I have to load it again from my PC back into the predator?

ok....thanks

I have a 99 SS Camero w/LID, Filter, CAI, LT's, SLP loudmouth 2 catback. About 8 months ago you provided me a custom tune for these mods which seem to work okay....now I am considering replacing my ls1 intake with and ls6 intake. Do you feel the tune should be re-done after this mod, better yet, do ...

I was kind of thinking this was going to be the answer I was going to get, oh well what's $185 bucks...haha
mike, your always a lot of help, thanks again.

1999 SS, SLP LT's, SLP LM exhaust, LID, K&N filter, CAI, SLP 85 MM MAF, still using the stock hood ram air as well as the CAI, diablo tuner.

With the stock MAF I get nice response from the LTFT's and can tune them with the diablo.....when I put on the SLP 85 MM MAF, my fule trims go to values of ...

This is going to be long so I hope you have time to read and reply....You have helped me a lot with this situation, but now it has taken another turn for the bad. To bring you up to date, I purchased a tuner from SLP for the 99-02 Camaro, it did not provide the tuning parameters for LTFT's or ...

slp's was something like 2007, and another site i went to was an odd number as well, i think they use their part numbers. but since i posted this i went to maryland speed and found it...but again not sure if it is the lateest rev of the tuner.

mike...i have searched out where to buy this model of tuner. what i am running into is the same situation i had when i bought the one from SLP. by this i mean, they call it a diablo tuner for 99-02 camaro, but their part number is never U7198, similar to the situation i had with SLP. can you tell me ...

I'll do that.....and again thanks.
