After several months of work I finally was able to get my truck tuned. Previously the motor was all stock...just intake and exhaust. Its a whole different animal now. With a p1sc, HT1 cam, 4l80e full exhaust on e85 it made right at 500whp. I cant begin to describe the smile it puts on my face lol. I sure am happy with my 4.8.

 

Damn that's some good #s how much boost are you running? What fuel system upgrades have you done?

 

Thanks man... 11 lbs. I'm using a single walbro 450 in tank pump. I converted it to a return style setup with an aeromotive regulator. Running id1000 injectors.

 

Very good numbers for that set-up. Curious on what you did to convert to return? Swap rails?

 

Thanks.... I ran a -8 to some aftermarket rails and used them stock feed as a return. The rails were for an ls1 so I had to weld new brackets to them for a truck intake. It was a little bit of a pain but I got them for free so I can't complain.

The only thing I want to change is switching from my tial q blow off valve to something recirculating... On the highway it's LOUD lol. I'm thing of going to a tial QRJ or a turbo smart big bubba. I'm hoping that recirculating it back into the intake will quiet it down.
