so im pretty sure there are no compression problems or boost leaks. it just might be my shifting, i have driven my car 4 months in the last 2 years. i did tune my air and fuel but i didnt change the timing. i ran a 12.9 on pump gas and no n2o at 106mph. i was told that at 120 mph was usually a 11.5 1/4 mile pass. as the day went on my n2o runs seem to get richer so i am thinking of changing the fuel jet. its wierd, the car would either spin like crazy or completely bog and die off the line. as for the the custom mods: dual intake= almost identicle jwt piping and low speed drivability with k&n filters dp=2.5'' that came with the turbos tp= 2.5" stainless steel hard pipes= i wasnt using them fmic= bought from charles park not sure of the brand or if he fabbed it himself
