And you did say you are taped into the MAP sensor. Question is are you taped in to reference MAP Voltage or are you taped in to modify MAP Voltage? Easy way to know is is the MAP wire taped or spliced.

Again as I explained above, if you are modifying MAP Voltage to adjust fuel you are infact making slight timing changes. It's just a by product. I actually like to think of the timing as the main change and the fuel as the byproduct as the timing is the meat and potatoes.

You never did get back to me on what Jets you use, I'm curious to as how they scale together in relationship to other cars I've jeted on. It'll give me an idea anyway on how "out of fuel" this car really is in the 450+hp range. Obviously you have proven our fuel pump is not a problem. and injectors are a simple swap. The only question is is there a need or not for a true rising rate regulator and the need to adjust fuel pressure. I don't think so.
