help i recently brought a chipped up p28 with a mugen chip in it it runs smooth and all but i was going to go back to stock when i plugged the p72 (virgin) back in gsr it feels a lot less responsive and it is definitly not getting the horsepower it originally
had before i swapped the ecu could the p28 have messed something up the p72 feels like its choking then when i plug the p28 back in it feels fine what could be the problem and i tried resetting the ecu's but its a no go and its definitely not just that the p28 chipped gives it more power there is something wrong can any1 help?

 

Sounds like its in your head. Are you throwing any codes? The ECU controls the engine. Do you think it broke your engine? That's funny.

 

ha ha!!!! not funny, no i don't think my engine broke did i say that ? i just want to know if its aproblem with my injectors or something like that

 

up anybody help or comment minus then negative ones thanks
