This 2008 5.3 Silverado is one of our employee's personal vehicles, and has been a pretty cool little project.
We started with just a dyno tune on our Mustang Dyno and HP Tuners.
After that we kind of lost control. We convinced him to do a BTR cam swap, and Texas Speed long tube headers and x pipe.
Hey, while we have it apart, let's port the heads some!
He was thinking ahead with the cam choice, a BTR / LJMS stage 2 turbo cam, with the plan being going turbo down the road, but that plan changed, as they do.
The truck was running fine and made 281whp (stock was 224). The transmission was hurting the numbers on the dyno, its a stock 4L60 4X4.
Then, our friends at TorqStorm Superchargers paid us a visit since their shop is less than an hour away, and we decided to use this truck to design an intercooler setup for their current blower setup.
The intercooler is similar to our turbo kit intercooler, with the only differences being the BOV/Bypass valve flange, and the aluminum piping from the supercharger to the IC.
While we were installing and designing the intercooler/supercharger system, we upgraded the fuel system with ID 1050x injectors and a Walbro 525 fuel pump.
With everything installed, the truck made 455whp and 503wtq on the mustang dyno. This was on 93octane with a stock catback, converter, and transmission, only running it to 5500 rpm.
So, a few days later, who would have guessed that his transmission went haha! So, that's where we are at as of now...
Coming soon will be a built 4L60 and converter and E85 with Flex fuel sensor

Draining fluids...
This truck was the definition of boring.
engine torn down for the cam swap, DOD delete and head work
Did a valve job while the heads were off, since we have the equipment in house
Decked the heads just enough to ensure they weren't warped
Heads are back on and cam is installed
Headers getting ready to go in.
Added a cheap cold air intake to get by until it got boosted, as this is his daily driver. The red valve covers make it faster right?
