Well, right now I have the stock TPI and heads with a mild street cam in my 355. I am getting a Holley Stealth Ram, AFR 195cc heads, and an agressive street/strip cam. I know nobody will be able to hit the nail right on the head for a perfect PROM for a setup like this, but could you guys give me an idea as to what I have to change and by about how much? I want to get a PROM that is acceptable to even start the engine with. I'm pretty sure I can't use my chip now, as it is very close to stock. I'm assuming this because I would think that it would run waaaaay too lean and could possibly cause engine damage. ANY help would be greatly appreciated. Thanks in advance.

 

read up on the arap bin

 

Where can I get this bin? Is it compatible with the 730 ECM? You think it will actually be close enough? Thanks again.

 

I just did some research and the ARAP bin is only for MAF cars. I have the speed density system. Any other suggestions? Thanks.

 

Have you read programming 101 on the DIY-EFI.org website?

 

I believe you are looking for the AUJP1350 bin.
