Any way to Disable or provide false info from the MAP. I keep on getting engine over boost codes. I know of the ppe code eliminator also but if i spend that kind of money ill just get efi live

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......

take the hood off or open it up and have someone ride on the front while you drive down the road.....

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
