Pretty simple question. Where can I get a chip from? What do I need to tell them to make a chip? And how much on average does a chip cost.

My car was originally a 305TPI and now its a 350TPI. It runs really rich. I think its because the guy that did the swap didnt change the chip. Any sugestions?

 

is it a stock 350?
is it running 350 injectors?

 

Best option when making a 305/350 swap is to buy a stock GM 350 chip ( about $60 )and after everything is running think about a custom chip.

 

www.fasterproms.com will make you one for $350. After that, you can borrow their DIACOM and it can give you readings and you email it to them and they send you a new chip. this goes on a time or two more till they get it nuts on for a truely custom chip. Used them and liked them
