I have been tuning it myself. Bought VMP’s pigtails. There was some voltages that needed in the tune that needed to be changed versus my 2016 imrc voltages

Mine is fairly similar. Top left supplies vacuum to my 2018 manifold with IMRC’s functional. Top right brake booster. Bottom left Procharger supplied vacuum block. Bottom right manifold vacuum.

http://injectordynamics.com/injector-selector/ Cool calculator at 7500rpm ID1050x would roughly be 75%DC vs 85% with boost reference vs not at 12psi

Good example of what boost referenced should be doing.

I would say that may be normal. I have a P1X as well. And have free spun it as well before installation and I believe that sounded similar. The gear box are straight cut gears and will be noisy. When you stop it spinning probably what you are hearing may be just the inherent backlash of the...

About install a turbosmart in that same location. Did you need to do any trimming when reinstalling the front clip?

Yes and Fore even recommends return line

Cool! Thanks just getting a feel with ballpark horsepower levels where I may want to target my boost on my 2016 P1X. Finishing up my Fore dual pump install now.

Nice!! what boost were you at for this pull?

Good idea to also verify the BOV is closing properly

I’m running the 2018 manifold as well with functioning imrc’s. I actually rigged up my GoPro to record the actuators to see if they were working correctly under WOT

Not sure about you only seeing 1.35 load I’m seeing almost 1.7 but your MAF seems relatively ok. You running the Imrc’s???

Like he said airload pretty much. At standard atmospheric conditions 1.0 air load would use 14.7 psi of air. Under supercharged conditions at 1.3 load could be .3x14.7 or 4.4psi of boost. So with what psi are you seeing or trying to target. Normally I believe if you were seeing 9-10psi of boost...

I see that now on the load. like you said maybe IMRC

I see 27 @ 5500rpm and 22 @ 7100rpm but the knock sensors seem happy in his first log.

Is 21ish degrees of timing a little much for just 93 octane?

Cool thanks. Slowly installing my fore double pump system now to run E85 and the 4.5” pulley.

think I’m at 9-10psi with the 4.75”. Any feel at what the 4.5” would produce? I shift around 7,500rpm. Thanks

On the car for 6 months. Plug and play BAP for 2015-2017 into the throttle pedal. $375 shipped.

Have the 2018 mani with P1X on my 2016 also and seems to work pretty well. Knock on wood my IMRC’s seem to function properly. What pulley size and boost are you seeing In your car?
