I did some testing, after adding an external wastegate to my B-1. I am overfueled and was getting up to 53 psi. before the wastegate.
With wastegate...found 45-46 psi (outside edge of B-1 map) produced more HP and 125* lower EGT's at my max fuel level (PM3 on #9).
Find it interesting that at lower settings on my PM3 (less fuel)...the lowest EGT's were around 40 psi.

My conclusions are - no benefits in higher boost than a turbo is mapped for...regardless of how overfueled a truck may be!

exactly! there's a reason compressor efficiency maps exist!

Thanks guys, I am going to adjust it this weekend. What is a good rule of thumb for adjusting the length of the rod? or is there?
