8-9 psi stock crank pulley, stock blower pulley. 5.3 with dual exhaust, stock exhaust manifolds, stock throttle body, stock airbox, stock longblock.

Another guy using the same blower and adaptors saw 8.8 psi on his 5.3.

How much hp/tq increase did you get from it?? Seriosuly thinking about finding the funds to get one for my 99, down the road..

I don't know, its still only running on a base tune. The wideband is maxed out rich and im sure there no timing in it. I sent in a data log to Justin so the next tune should run stronger.
I can already feel a good increase in power but im hoping for more. I plan on putting it on a dyno next time there is a dyno event near me.

Post results when you get them, curious as to how much of an increase it is, do you have numbers from before by chance??

No, but it was bone stock.

Ok cool..

All I know is I couldn't do this before the blower....

Nice!!!!

awesome install, any updates?

So far so good. Got all of the bugs worked out. I probably have over 1000 miles with the blower now..

Still working with blackbear to get the tune finalized but I must say it is a slow process working with him. I guess he is a busy guy.

I have some long tubes I need to install. I have plans to get a 90mm throttle body (still running the stock truck tb).
I want to replace the G80 with a truetrac.
Ill finish it off with a vinci trucker cam and smaller pulley and call it a day.
