12 psi overall. It goes up to 17 psi in 1st gear but by third im barely getting 11-12 psi. Im still running the lightest JGS wastegate spring which is 7 psi then relying on my booost controller for more. Im gonna change it out for the stiff spring.

To the comment about not seeing hi intercooler temps, come down here to houston and I guarantee you will see some elevated temps. 100+ ambient sitting in traffic.

i come from vegas desert, 115-118 deg out, even at that my intake temps were never above 150 unless i was just idling forever

however if your 120 at start of the track it should not be going up that high by the end of the track. If i know its going to be hot at the drag strip and vehicle is sitting ill spray my IC with a water spray mixed with water/alcohol to help keep temps down. Like said earlier may wanna consider some water/meth. also where is your AIT sensor?

Let me know when you go out again. I'll meet you up there. My truck has been a best 7.1@94mph. Get your 60s down and you should be low 7s for sure. My IAT started at 103 and ended at 119.

what's your current suspension setup? I can help you to get it to hook. I didn't get a chance to watch any of your passes and after my first pass I was chasing problems on my rig. I'm having ignition or voltage issues.

It's stock with a flip kit and 1" lowering shackle on the passenger side to combat chevy lean.

I've been doing some reading so I have an idea what I need to do. I bought spring clamps and plan to clamp the overload in the front. Also caltracs. The race star 17" skinny front wheels supposed to come out in October. As it is now with the 20" wheels up front it has at least 2" of reverse rake and the truck sits higher in the front by about an inch to begin with. 3" macgaughy spring.

I did manage to improve to 8.27 but that's still spinning its *** off to half track. Boost is going up to 17 psi in 1st gear and shredding the tires. I'm going to put a stiffer WG Spring in and dial the boost controller down hopefully to get better control of the boost.

Have you thought about running a different boost controler? Doesnt seems like yours is working to well. My ams-500 is not as flashy but it hits the mark every time in every gear.

Congrats on getting out to the track.

my bet is on suspension. with a flip kit you really need to relocate the rear shocks. they are laid the F out and not able to do their job. loosen every bolt on the front and rear suspension until it all moves freely. I'm sure 90% of this forum has their suspension parts over torqued. front and rear. I am a HUGE believer in double adjustable shocks now. they are expensive, but I have gone from 2.1 60' times to 1.59 and pulling a tire by only making a shock adjustment and touching NOTHING else. tonight I pulled a 1.47 on drag radials.

I really wish someone in a full size would try spring sliders. I'm using them and LOVE them. the suspension is actually able to do its job and it takes away the "arch" motion that is inherent to a shackle.
