I finally got my tune all worked out and am very happy with the results. I made 342RWHP and 351RWTQ with an average 12.5 A/F. I was having some fluctuation throughout my rpms with my A/F. It's all ironed out now and I can't wait to install my new suspension goodies and get well from my accident. 12ohs or high 11's here I come. Also, gonna put the hefty GT on a diet. I will keep you all posted.

i'll take that bet. i've had three different turbo cars dynoed many different times and the first time for two of them (not the stang bc i already had a wide band o2 sensor and therefore an extra bung for the dynos wb) we had to drop the downpipe and drill a hole and weld a bung in for the dynos wide band o2 sensor. you want the wb o2 sensor no more than 36 inches from the turbo for the most accurate reading...so the tailpipes are out of the question. after the tune you simply plug the bung (old sensor works fine) and go on you way. what is the point of putting your car on a dyno if you cannot measure the a/f ratio??? other then just to see what it makes to the wheels you just wasted your money aixtreme. racer02 your a/f ratio looks fine...it is not way off and is pretty damn conservative for your #'s
