Recently replaced my blown 305tpi and put in a 355tpi. I know about the different size injectors and the knock sensor but from what I have read here it seems that I'll need to replace my chip also. So whatever chip I decide to go with, do you order one for a 305tpi which is what my car originally had or order one for a 350tpi?? Maybe this should be obvious but I'll roll with the punches since I'm the new kid on the block!!

 

Do you have an automatic or a stick? If you have an automatic, get the 350 automatic chip. If you have a stick, there is no 350 5-speed chip. But you can use the 305 5-speed chip, or get a custom chip. There isnt a "magic" off-the-shelf chip that works with every car. For that, you need to get your car dyno-tuned and have a custom PROM burned.
