2012 GMC Sierra SCSB 4.3 to 6.2 Swap GMT-900 NNBS

It’s at 11 now and I run E85 at the track I actually need bigger injectors. Lol it’s maxed out for a 1900, I need to step up to get to 1000 hp. It’s fun at 750 rwhp but I want that 4 digit power for some reason.

Did you modify your wiring harness when installing the blower or just tuck it in differently. I was looking at my truck wiring harness wonder how I would route it if I put a Whipple on here. I don't think it would look very nice laying on top of the blower like it does on the stock intake.

It’s a tvs kit made for the truck so magnuson integrated it into the truck pretty well.. I think the harness is behind the blower but it’s been on there for 6 years now so I can’t remember I’ll have to look.

Idle clip for those interested. 214/224 113.5 + 8 LSA .553" Lift VVT camshaft. 6.2 Liter L94 engine, DOD delete, Speed Engineering headers and single 3.5" exhaust with giant Walker DynoMax SuperTurbo muffler part number 17789. Sorry, no sound clips with the Speed Engineering muffler. It was just waaaaay too loud for me and I could not wait to change it out for something quieter.

I replaced the 3.23 rear gear with 4.10 gear and Powertrax Grip Pro differential last week. What a excellent difference in around town drivability and acceleration. This should have been my first mod. Love it.
