Does Hot Cam require ECM Changes

I got my engine started. It has a Comp Cam (very radical) I have to open the throttle on the TPI throttle body for it to start, but when I do it will run. My question is do I need to make ecm changes, or are there any other changes I should make to better tune my engine for it's mods? It is a 350 bored .060
12 to1 compression pistons. I am running an 86 TPI unit with MAF. It seems that the engine is needing to idle much faster than stock idle speed. Thanks for help guys

Yes. You'll need a custom tune.

Start reading on the prom board and get ready to dig in.

U should have learned to tune on the stock setup first before doing mods, it would have made your life alot easier.

I know you are right 3.8TransAm, but my engine wasn't stock from the begginning. It was a carburated engine and I wanted to go TPI
