Thanks! Really happy with the numbers it put down. Feels pretty strong all the way through in my opinion, but you can definitely tell when it gets into higer boost around 4k. I have the dyno chart in my post in the Sn95 section.

So what's weird is that we placed the cams differently this last go around to get rid of tq and shift the power band right lol.. It did the opposite lol.. Picked up like 80ftlbs, and moved the peak over lol.. I think there is more in it on the top end but we stopped tuning which is totally ok.. I would say it'll make 875 @7k after we tune more :)

How do you like that D1X? I was looking at one of those for another project as I have a P1SC sitting around and I seen that they charge like 1600 to convert it to a D1X.

If you have a p1sc stick with it. If you are buying new spend the $400 or so for the upgrade but I don't think spending $1600 is worth it unless you plan on hitting 1000rwhp. With that said I like it and am very happy with the power output.

I have new numbers after I installed the F1A-94, but the rest of the combo is the same. Once I get this new EFI setup and running correctly, I should have even more. Going to tune it on 93 and E85, see if we can't inch up on the 1K mark.

You shouldn't have a problem getting there with that blower.. That's my plan with the YSI-B not going to change pulley combo's or anything.. I'm out of blower at 6400 rpm and spin 8k lol. I'm thinking I'll pick up 140rwhp

Any new combos out there?
A few guys have recently ditched the leaky Pro-Charger Pro-Flo Bypass valves and the results have been impressive. That's my next plan... Dark Mach gained 3 lbs of boost as well as 3 mph+ trap in the 1/4 just by changing this valve out..

https://photos.app.goo.gl/fc860CcDQv5yUynX2 these were my results, NOT impressive. Left is the new BOV, Right is the Pro flow. Save the $300-400 if you can.

Negligible difference. No adverse affects in doing it but IMO there is likely less than a 1% chance you gain anything more than the .2 psi that I gained. I think DarkMach1 likely had a dud valve.
