Need Help! Upgrading Performance 2015 PPV 4x4

[Citi]

Hello!

I am totally new to this forum but it seemed like the place to turn to get some input.

I am looking for input on the best/most cost effective performance upgrade I could do to a 2015 4x4 PPV.

I am totally new to this sort of thing but want to maximize performance and budget is fairly open. I know cold air, headers, exhaust, are all going to help; what brand would one suggest?

1. K&N Cold Air Intake #60-3082
2. GIBSON PERFORMANCE HEADER, STAINLESS #GP137S
3. GIBSON CAT-BACK DUAL EXTREME EXHAUST SYSTEM, STAINLESS #65668
4. Airaid PowerAid Throttle Body Spacer 200-543

Any changes or additions?

Looks like a good start but before you make any of those changes consider buying a Tuner and optimizing what you have to have a solid base line. The Tuner will also help you dial in any future changes you make.

I wouldn't bother with the TB spacer. If you really wanted to increase air flow look at the FAST TB. I don't know if they have one for the direct injection engines yet. I had one on my Silverado and after tuning and with the same type of exhaust you have listed it moved some air... Was it a huge increase, no but it did help with the cam. And ^^What he said^^

How was the Gibson exhaust? I've read mixed reviews. But the idea of true duals appeals to me. I also can't find many youtube audio clips for the Gibson.

To OP (Citi), why gibson vs Corsa?

And Citi, you can "pin" the rear exhaust valve for a couple quick ponies and a little better sound. Quick + cheap + easy.

By same type I meant headers (Eldebrock), y pipe and high flow cats (flowmaster) exhaust (Magnaflow). So not any specific Gibson experience. Problem I had was finding vendor's who built the stuff, just like now with the 2015 Tahoe aftermarket. That truck was built for a turbo and flipping the passenger side header allowed for a near perfect mounting point for the turbo housing.

I'd get a good tune on it first. If that don't satisfy your itch ....... Magnacharger TVS supercharger , headers and a Corsa exhaust. That should put a smile on your face.

Best of luck !

Hell yea it will. Grin from ear to ear and stoplight to stoplight to traffic court...

Diablo...

Diablo won't be able to tune for any true mods.

 

[LGSONE]

True, unless you take it to a diablo dealer who has a dyno and uses the CMR software you will only have what some bolt ons can offer. But as Jennabear said SC or any FI will require custom tuning.

So which brand would you suggest?

 

[JennaBear]

Someone who uses a true tuning software such as EFILive or HPTuners.
