305 tbi to 350 tbi chip install??
Ive already read the sticky and I didn't read anything about if I can install the 350 tbi chip in my 305 tbi ECM. Do I have to buy an ecm?

as long as its a 746? ECM i believe you'll be fine. Me i did the same but i have a 88, im the unlucky guy that has a diff ecm than most other f-bodys, so i went with EBL flash, im actually waiting for my stuff to get here 
if you are getting a chip over the internet i would look deeper into my options... i myself had bad luck with buying a chip from sme over the internet website and it made my car run worse than stock. If you are planning on performance i would check else were

i figured he was speaking 305 tbi to 350tbi swapped and he needed a new chip. if you still have a 305 in car do not get a 350 chip what so ever.
