another 03 chevy truck twin turbo. this is my friend's 03 chevy truck twin turbo with 11 psi(to start). we just installed a 370 FI motor and 317 heads with a little port work.this is my first SD tune that i do so i guess i'm going about it the right way,i did a 3 bar SD tune on it with 11 psi boost and have ran 18 psi on the street and let me tell you this truck is crazy. Need to swap out the gears it has 4.10 and he had to go in to OD on the last run.we are going to intall 3.42's and hit the track again see what it does.well her is a vid on the first time out to the track.firts runs were 1/8 mile runs and the last a full 1/4 mile run.truck takes off with 0 boost.we are from the same area where jj is from, the guy with the nice yellow turbo truck.
