I chalk this one up to a succesful test still though - showing that the modded rail moved the useable HP down in the RPM band. Once the new relief valve is in I will test to see if the modded rail can make more MAX HP
PS - This means more TQ for same given HP, does it not?
TG-
Good stuff! Thanks for taking the time to do this comparison.
The gain in your low end power practically mirror the dynos you did when you got the modded CP3 first installed. If you gained 100 HP in the low end with a modded CP3 and presumably healthy relief valve back then to get your 60x HP, then I can't wait to see what the modded rail + healthy relief valve dyno will look like!
Further, this latest dyno graph very clearly doesn't have the goofy ~2000 rpm dip when the rail pressure typically briefly runs low like on more stock-like trucks running a TST.
