The tables are looking better though, good job.

And Dame smells like fuel. We took it step by step a couple times. Really looks like the FPR for sure, but a question came up. Anyone know what the BENCH pressure should be for his 93 fuel pump (non-supercharged)???

New to the post. . . . . .Are you modding the MAF? or Porting the Throttle Body?? If you are Modding the MAF what are you doing to it and why? Your not going to outflow it! And if you are porting the Throttle Body, remember that velocity is the key in a N/a. I've heard from the fiero guys and ZZP that OBD 1 can't take much customizing with out some kind of AFC. As for your knock issue, WTF? 15* @ WOT?? You should be like 40* and with no knock at all! Did anyone else notice the trans temp?? Is that reading disabled on that year? That seems really High!

It must have been the fuel pressure.
30-40 psi is low.
The pump is rated at 60 psi.
With the vacuum line pulled, the fuel pressure should be about 56 psi.
With it connected, it should drop about 4-5 psi.
My original FPR was low by about 5 psi.

I'm wondering how this MAF mod would compare between L27 and L67. Volume and flow rates are totally different. It may work for one better than the other, with the L67 not necessarily being the better achiever from this.
