Hey there guys,

Just installed the PSI exhaust on my car, and I had already had done the GIAC flash about a month ago, and my question is.......do I need to have anything reprogrammed or tweeked with the addition of the exhaust and 100 cell cats????

Thanks,

i don't believe so....i believe the chip prior to the exhaust was just not being optimized...now that you have the exhaust with the 100 cell cats, you have reduced the back pressure and are now optimizing the reprogramming of your chip. not sure if the psi exhaust mufflers are any less restricting though....

 

No need to do anything.Your exhaust is very unrestricted so just enjoy.
