engine gsr with skunk2 intake manifold

New cap
New rotor
new wires

timing dead on

when i go to rev it, it lags and then goes alittle bit, when im driving it, i floor it and it feels like it is a single cam, it accell super slow.

 

What engine management are you running?

 

im using a stock GSR ECU P72 and then i tried a chipped p28 with stock base map and then i tried a p28 with s2000 tuned with a jun chip and they all still do the same thing. at first i thought i had too small of piping cuz i used an ex exhaust system but then i got it repiped to 2 1/4 and it wasnt as bad becuz the ex had the cat there now its just straight but it still doing that.

i checked if it was the tps and tried others but didnt fix the problem.

(i running a LS throttle body FROM A 94 LS)

I may think it has to do something with my fuel becuz im using a fuel rail and regulator from a really old LS and i forgot what year but the regulator bends 90 degrees
