it will act like in limp mode and pop/bog at about 2600ish but if you feather it till 3000 it will rev till 9000 no problem,
idles around 1100-1450ish, my maf is good, tps is good, im looking at maybe the air reg, aac or coolent temp senc?
any INTELLIGENT opinions would help at this point, i want my baby back on the road! even at full boost she gets better mpg's then my chevy 4x4! gas cost to damn much :cry:
