Guys with the newest flash VXCF9 and custom tunes what kinda boost numbers are you seeing?

Running SRL i cant break 22psi. EGR valve is plugged in and intact

Return to stock I can hit 28-30psi

Boost numbers will also decrease as the efficiency of your truck increases.

I am running matts SRL with full egr system still in the truck and seeing boost numbers up to 30ish. I will check tomorrow just to make sure and will repost. Going on a 3hr long trip tomorrow so also going to hand calculate my mileage to see what I can get on that kinda trip.

I will post back with the boost numbers though. Does having an EGR delete lower your boost?

I'm running Matt's SRL+ for studded trucks. I also have the VXCF9 flash and see 30psi regularly. Try just rolling into the throttle and see what happens. I know if I just mash the throttle to the floor it doesn't build as much boost.

Yes, There is less waist from the egr system, so there is less air needed
