first question which i just asked in the wrong section. will an exhaust leak cause enough of a power loss to make it hard to chirp 3rd in a mach? second question is, can you buy a used diablo programmer and jsut plug it into your car? or is it made for the first persons car? i know some ls1 programmers are for the first buyers car

 

im pretty sure diablos only work on the original vin# thats inputed...also, it depends where the exhaust leak is. if its before the mufflers, it could cause power loss. after, it shouldnt.

 

the exhaust leak is up where the x pipe connects to the manifolds

 

yeah, that could create a loss in power, since your losing air, the velocity of the exhaust gas going to the mufflers will be slowing down.

 

yea what ^ said
