its done. I maxed out the stock flex fuel injectors and ended up installing a walbro 450 and 100lb injectors on stock rails. Im running 7psi off the spring but not seeing much power. The turbo spools really quick and gets to full boost fast. im at 450hp. Goin back to get a speed density tune on the 25th and bumping boost to 12 psi with a hallman boost controller

Here's a dyno pull video from the first trip to the dyno I had a small exhaust leak off the wastegate that is fixed now.

 

Congratulations, Sounds and looks goods man! Do you have a 5.3? Is that cam making it kinda soft down low when driving normal or boosting? Maybe stall and gears are helping it out and is the right combo for turbo crew. What did you do for final exhaust and any idle clips?

I'm looking for guys with results that are running turbos and bigger cams that lope. Especially ex and crew cabs.

 

Yes its a 5.3...not at all the cam is good I had it speced by Pat g for daily driver with nitrous he said it would be slow spooling the turbo but it kicks in fast. I just came off the downpipe with 3in pipe to a bolra muffler also have a cutout before the borla

 

Put down 556 at 12psi today

 

Nice,
How's it feel driving around town?

 

That's nice I bet your lovin it

 

Haven't drove it much but I'm loving it! I'm ready to hit the track! I'm runnin a hallman boost controller with the 7lb spring in the gate

 

Good numbers for the 5.3 Get it to the track. Remember it's hot so cool weather will make it faster.

 

Thanks for your help helping me with fuel pump..I put the return line on and no more problem with high fuel pressure
