hmmm, get your voltage reading at the highest point before it kicks the light on and some how fool it with a resistor or something......

well if i were to throw in a resistor and lets say it alters the voltage so it wouldn't throw the code to de-fuel it would instead add more fuel than its doing now then, right??

and then my only trouble will be adjusting the waste gate to hold more boost

problem with a resistor is that it is the same no matter what, i think that will cause problems, i could be wrong though....

you can do your taxes with EFI live. But theres more other things i have to beef up before i get efi live, like my front end, and lift pump. and i got a 4.8k credit card bill to pay
