I have a used kit I bought from Cory harris a long time ago to go on my LQ9 06 Silverado.I still have the kit and its not on.What happend was I bought a used 06 Escalade that had a radix on it.I have the Esc. sold to someone that didnt want the radix on and of course there was no stock parts to go back on.So i swapped everything onto my truck. This has a 3.3 pulley on it , what do you think this should have for boost? I do have longtubes and high flow cats.
Looking forward to your input,thanks

 

I think around 4-5 psi maybe.

I was making 7.5psi on my stock LQ9 with dynatechs with a 3.0" pulley.

 

Oh yeah, CONGRATS on finally putting one on!!!

I think you should put a 2.9" pulley on it. The difference is amazing compared to what you are running and it should be about 8.x psi.

 

Thanks,ya your right , but im toe dipping,I do know Big tex's truck runs bad fast with a 2.9

 

Yeah his ran real well with the cam he had in there for how heavy it was.

 

Hey this thing doesnt want to idle with the NA tune,rev it past 1K and shes smooth and fine.I gather its the load of the SC and way fat .


I just finished swapn these this afternoon

 

Getting it to idle was a bitch, but I got a file for HPTuners that automatically calculated the idle numbers I needed to plug in. Maybe you can find something similar for your EFI live. Mine idles at 750-800 now.

 

Glad you finally installed that thing Gonz. It took you forever to do it though. 3.3 pulley should give you 5 psi I'd guess. I started out with a 3.0 then moved to a 2.75. The 3.0 was really just right for a driver. The 2.75 ran stronger, but brought some idle part throttle transition quirks.

I can help you get the idle correct. Have you adjusted the tune for the larger injectors yet?

 

yes injectors scaled.email me direct so i can give you the low down bro
