I finally got my car back on the dyno day with new hellion sleeper kit. The mods are listed below. I can't wait to get back to the track and see how it feels with almost 800 FT LBS. Jon Lund JR did a great job on the tune and the car has more in it if I want to push a little more.

Stock engine with OPG/timing gear, Return fuel system, ID 1050X, Pump E85, Unported 2018 intake, hellion sleeper with precision 6266 JB, 6r80 245 3c stall, 3.73 gear, boost leash on CO2, 14psi

Hell yeah man, happy you got her up and running. Turbos are SO FUN on these cars. Congrats.

Excited to see how it runs at the track!

Is there any specific reason you went with CO2 for boost control?
I just heard that is the way to go. I think it would have been fine without CO2 but it works great. I took the car to the track today and it will be a beast when I get it dialed in. I ran the first pass on 10lbs and the second pass on 12lbs. I could not build any boost on the line.

Nice mph! Is your engine stock besides OPG/CS gears? Congrats.

Fantastic results, that thing is moving. I have the top mount setup and love it. I feel like I’m losing some time in the auto shifts though, almost feels like it’s shifting too soft. How hard are your shifts hitting on those passes?

It shifts hard under WOT but not sure how hard. Who tunes your car? How much timing are you seeing?

Engine on the car is stock other than timing gear, oil pump gear and 2018 intake.
