I just swapped out my 305 tpi in my 87 Iroc and put in the GM vortec head crate motor and I bought the tpi intake and used the tpi setup on the 350 I also put 24lb injectors in it. I have a chip for a 350 with 24lb injectors but it is not specifically for this combo. the car runs good except it has trouble idling. It is real choppy at idle and when its cold it wont idle at all but as soon as you give it a little gas it smooths out and actually runs very well. I heard that I might need a custom chip for it and that would solve the idling problems but I dont know where to get one that isn't $350 and I am still not positive that it is the only thing that is giving me the problem. any help will do thank you
