Just thought I would ask a question. I am building a 396 SB for my 1992 Form 350. It will have a Magnum Comp Cam 244/244 .600/.600 Trick Flow R heads, Mini Ram 58 MM TB and all the usual stuff. My question is will I be able to use the Speed Density system with I assume a custom burned chip or will I have to get something like a DFI? Thanks.

 

A tune will be a definate. DFI, or DIY prom, the choice is yours. DIY is a bit more work, but less expensive. DFI, on the otherhand is more money, but less work. DIY prom IMHO, is a fantastic learning experience, and rewarding. Do you still have the MAF set up? You can DIY prom with MAF too.
