So I stopped slackin and chasing tail to work on the truck some. Got GM AIT installed (maf removed) Bosch 127lb/1320cc injectors installed replacing the 80lb's. Also removed the Boost-A-Pump as it's no longer needed. I found out two walbro 450's will overflow the stock feed line if your using that as a return line with a aftermarket (in my case fuel-lab) FPR. Lowest I could go was 65psi, installing the vacuum line made no changes. Fixed that with a hobbs switch that kicks the second walbro on at 3.5psi, so i'm running a current base of 58 confirmed with a autometer pressure switch i'm logging. Hope to keep these clean with a Jeg 100 micron steel/mess filter and megna fuel 25 micron steel/mess filter, both e85 safe.

Lastly was swapping trans/engine fluids. Hope to get a new tune started tomorrow and get it ready for the dyno on Saturday. Also need to swap in some new 7s plugs just to be safe with a .022 gap.

Honest goal for saturday.... 800 wheel (roughly 1000 flywheel). Going from last track outing and weight, i was around 770 wheel. I also figured out my nitrous was on and off the whole pass. (50 shot) I made a post on Hptuners about it, but not much help. I didn't command it, but my staging shot seemed to be on/off 1 second apart the whole pass like it was dropping signal or something. This explains some of the 15psi/134 trap/4580 weight. Hell I wish it stayed on the whole pass not just half now lol. So that said well see what it takes to make the numbers. I'll keep turning her if she takes it. Maybe a 800 tune will go 9's?! or go boom, either way it's going some where.

God speed, i'll keep you guys posted.

Care to explain your choice of lubricants? I am intrigued by the choice of 20-50 VR1, which is fairly thick with a higher ZDDP package, and adding the STP with viscosity enhancers and extra ZDDP. Are you still using 02 sensors for closed loop operation?

Let me see...truck, chase the girls. Girls usually win. Anyway best of luck. Everyone is watching this.

Man I just never could wrap my mind around 15psi 134mph on your truck, you have one of the best setups iv seen but still seemed a bit wild, don't get me wrong your truck runs eaither way but you were going 14mph faster then me on the same boost lol. Eaither way best of luck on the dyno and track, cant wait to see what she does!

How many lbs/hour does your turbo flow?
Did they tell you when you got it? Would it flow close to what a normal 80mm does, but spool better?

Thanks guys!

I've always run thicker stuff with a ZDDP additive. I ran 10w-40 up till 100k miles on the engine and then switched over 20w-50. I also swap every 2k miles.

My thought is I been boosted nearly 45k miles now and made over 500 wheel from week 1. I also been turning 7k RPMs for a while now. My bearings need all the help I can give them.

I also just replaced the factory 02 sensors last year lol, so yes sir I do.
