i am puting an ls in my 4dr and i have done the dpfi-mpfi conversion on my stock harness, im running a obd1 jumper and an obd1 dizzy, with a p-28. i am having a weird problem where it likes to bog down if i just punch it, if i ease into it i can run it hard.... im stumped. is there anykind of different harness that i can run or what are the steps i need to take to get this baby rippin..?

thank you for any help i get.

youre running a stock p28 on an ls?

 

yes....its what i had..should i be running an obd1 ls ecu...?

 

you should use the stock ls ecu or go and remap the p28 ecu;
