I am building a 91 350 to a 355 that should be pushing around 375-400hp but the computer that I have is still the 87 305 computer that was in it before the swap. I was wondering if I should get a different computer or just get a performance chip or get a custom chip. I'm not very computer savvy and could use a little help.

Thanks very much,
Alex

 

What intake?

305 TPI computer is same computer as 350 TPI computer; only the tune on the chip ( memcal ) is different.
With a stock 350 swap, all you need is a 350 memcal in the 305 computer and a 350 knock sensor

If you plan on making the Hp you claim you will be up for a custom tune anyway.

 

FIRST tpi intake
