HELP! MY CAR IS ACTING FUNNY WHEN U GO DOWN THE ROAD AND GET ON IT STARTS BREAKING UP AND POPPING AND ACTS LIKE IT TRYS TO CLEAR UP AS U GO ON THE BIG END I AM HAVING TO RUN AT 55LBS POUNDS OF FUEL PRESSURE WITH LINE OFF 2 KEEP THE O2,S AT AROUND 800 I HAVE A 52 TURBO WITH 50LBS INJECTORS AND A PRECISION CHIP CAN ANYBODY HELP
 
Being that the heads are different on the TTA vs the GN I dont know if they are the same but I use AC DELCO 42lts. I was having the exact same thing happening at around 18-20lbs and closed the gap on the plugs and whamo gone. Runs like a scalded beast now and no more top end sputtering.
