Hi guys, i have a 86 iroc that had a 305 TPI and how has a 350 TPI. but i havent changed the chip. i was thinking of buying a JET CHIP will this help and act like a 350 chip? car seems to run good how it is was tuned. but if this can help i will buy it. Thanks!

if its a stock chip that asnt been tuned... then yes u need a 350 chip. or u can just get a custom one tuned to your motor which will give u the most outa it. i have a motorvation strip chip in my 350TPI... could i tell a diff over stock chip?.... umm not really bc i did other mods at the same time.

some will argue that the stock chip isbetter or the aftermarket is better or the aftermarket ones are worse... nothings for certain in your application. i would get a custom tune... i would do all ur mods u wanna do for a while so that u just have to get it tuned once and save urself alil money

 

that is a great idea. i was thinking putting a exhaust line with headers and some injecters. mabey will help with the tune. do most locale garages offer this tuning service? like speed shops with dyno's?

 

no u need special tools to tune... dyno shops should be able too or i would look for a chip burner... like pcmforless.com etc they are $$ tho. or u could do it yourself if u got the adapters and software etc.

yea def get your mods done first. the injecoters def have to get a tune after the injectors. so get all ur mods done then go looking for a tune
