2017 Denali 1500 tune,headers,cat-back,cai

wildlyfe200 · May 31, 2017

I fell down the rabbit hole it all started with an AirRiad full intake and then I got to thinking. I need a cat-back exhaust, headers and a tune. Here is where I am at.

-Borla touring dual exit - http://www.gmperformancemotor.com/parts/19303342.html

-AirRaid full kit - https://www.airaid.com/search/product.aspx?prod=AIR-203-111

-American Racing 1 7/8 headers and high flow cats - https://americanracingheaders.com/collections/gm-truck/products/gm-truck-6-2l-2014-up-long-system?variant=29943904900

-Efilive flashscan V2 from Blackbear with email tune - http://store.blackbearperformance.com/EFILive-V2-Scan-and-Tune-GM_p_17.html

I ordered everything but the headers I have a local shop that I feel comfortable having install headers https://www.eastcoastsupercharging.com/ and if they are installing them I will just let them order them for courtesy. They work on mostly corvettes and camaros also trucks. My only concern is the cost and I am curious as to what you guys think about two things and some help with my decision.

-should I have them purchase and install the headers and "street tune" for $3149? keep in mind they are also installing the cat-back Borla exhaust which I am supplying. So $3149-$1775=$1399. minus the cost of the headers it is $1399 for the header and cat-back install and street tune.

-OR find another installer that I trust to do the headers and cat back install and just use Blackbear for the tune that is included with my flashscan V2.

I like the idea of having two different tunes so I can compare and see which one I like better and get to learn efilive and hopefully do some of my own tuning in the future.

Please no comments why don't you install everything yourself. I did the intake and would have no problem installing that cat back but headers are out of my league.

Thanks just wanted to bounce this off of you guys and see what you all thought.

No reply ehh. I decided to go get all done at the performance shop. I feel more comfortable. A few hundred extra for piece of mind.

Also anybody looking to tune their 2017's there vehicles here is a really neat tool that I will be buying.

Just an update. Looks like Monday of next the truck will be going in the shop still waiting on the headers. it's killing me. I about to put my exaust on just cause I'm tired of looking at the box in my garage.

Got the ride back. I am 100% happy well 99% I gotta ding 1% for the little grease stain on the seat. Nothing a little dawn and a tooth brush couldn't fix. Sounds perfect nice grumble and not obnoxious. The real magic was in the tune that Doug @ East Coast Supercharging did. Like a whole new truck. I can actually hit 5k+ RPM going through the gears when I mash the pedal. Not too aggressive but perfect. The only thing I notice though is when the truck downshifts the RPMs raise up noticeably. It did not do that before the tune. It is not that bad but I assume that is because he raised the downshift points.

All in all I had a good experience at that shop and would recommend. Here is a quick clip and some pics. Not the best video I will get a cold start tomorrow.
