305 to 350 PROM chip
 

do u kno where i can get a 350 prom chip so that i can swap it into my computer?

hypertech? Is the engine modded?

ebay usually has em floatin around

hypertech chips are junk just get a custom tuned chip. ill see if i can locate the site to post it up

edit- i cant find the website i thought i had it written down somewhere, but HardcoreZ28 told me about it a while back

If you want a custom burned chip, talk to JS Performance...they'll hook you up.

Correct me if I'm wrong, I thought the 350 has larger injectors then the 305 ( 305=19 and 350 21 or 22?) or there was some other module as well that needed to be changes as well?

Depending on the year, there are more parts involved.

For TPI cars with MAF setups, you need a 350 knock sensor, 22# injectors, and a 350 calibration.

For Speed Density cars (90-92) you need the knock sensor and injectors, and a whole 350 MEMCAL not just the chip.
