Hey i am new to tpi i just put a tpi unit on my 1967 chevy pickup and redid every thing wiring the works every thing is new i sent it to the local shop for tuning because it wasnt queit running right. Ten months late he gives it back he fixed one problem i had made a new one. Before i gave it to him it would start up and run ok tell u turned it off then it would just crank and u would have to let the engine cool off and clear the memory to start it again well he fixed that problem. But now it feels like it has no power and doesnt sound right at a idle i am way pissed. I mean it ran better when i had a carb on it. any info would help. Thanks
