Max seq. psi
 

What all is required to run say 15-16psi sequentially, as for controls?? pressure regulators?? if so where at?? What are the stock solenoids good up to??

People have had problems with the stock sequential system around 14-15 PSI. I remember a few trying to run it higher years ago and never really getting much past 15 PSI without having issues.

I thought I remembered Artguy running his at 16 PSI with the M2 ballbearing twins, but I could be mistaken. kwikrx7 had his running at 14 PSI with the updated BNR twins making about 380rwhp.
