Im gonna be buying back a TBI camaro I sold to my friend last year. I want to drop my 350 right in and use the stock TBI setup if possible. Buts it got a big cam, 234/242, .539/.558. I just want to know if the stock TBI stuff and computer can be tuned to run decently. Im talking a 13.99 tune. For the amount of money I put into the motor I might as well reuse it than sell it for a fraction of what I spent, so dont try to talk me into using different setup, I dont have the money. my only other alternative is an Edelbrock 600cfm carb and regular dual plane intake. Plus I love the choppy idle it has. So, either it can be tuned, or it absolutely cannot. Whos got the answer?

It most certainly can be tuned, but I wouldn't try it without learning the ropes on a stock setup first. Also with a cam that big the stock code is a little lacking, actually with that cam you're going to have to accept some limitations. Lucky for you Rbob's new EBL fixes all of this, the alpha-N mode will pretty much eliminate the need to fool around with MAP filtering at idle.

I tuned a 218*/226* cam on a completely new engien combo with no prior experience and it was difficult. It took me 3 evenings worth of tinkering to get it moving under it's own power and a week to get it to the point that I wasn't afraid to pull into traffic. It took me almost 6 months to get it "right". I can get it "right" in about a week now. So most of that time was spent learning how to tune the computer rather actually tuning the motor.

Two of my friends are pretty good at tuning, thats why Id like to keep the TBI. No way I could do it myself.

I second that answer - Do it! One thing I ran into was lack of fuel on the top end though, so be prepared to get bigger injectors or up your fuel pressure.
