I was referred to you to inquire about a tuning issue I'm having with my 2005 auto GT. I'm running under drive pulleys, air raid race cai, SCT flasher with bama tunes, 3.73s, and just an axle back. I've been working on the dyno for about a week now and my first run on the "race" tune was a blistering 277whp but with around a steady 15 A/F ratio and 47 degrees of advanced timing. I've heard that allot of 05s have tuning issues and we put my friends 06 with the same mods and tunes up hitting a 320whp without the timing and a/f problems. I'm really wanting to start adding more power but these tuning issues are giving me a headache. Thinking of heading towards the standalone but i know that's a bit of overkill at this point. I'm open to opinions and any advice you can give me. Thanks allot
