85 transam Tpi just dropped 350 need help
Hey guys i need your help. I just put a new 87camaro 350 in my ta and she lacks power like i was told she would. I heard I need to change the Prom chip as well as the ecm is this true. And if so where can i get a high performance one that will show me my ta's true power without charging me an arm and a leg, I dont street race anymore but I would like the extra torque to impress the ladies .Any help is highly appreciated.
Thanks
Thanks

I did the same thing. I just used an adjustable fuel pressure regulator and set fuel pressure to 46psi at idle. Stock is 42psi. Found this tip in a magazine and so far I'm not disappointed.
