So before I do a cam or a blower on my truck I am going to do longtubes, flex fuel kit and CAi.. Has anyone done these basic mods yet with a tune? Any dyno graphs? going to have the stock catback with a cutout installed to make it loud when I am out of my neighborhood and my wife isn't in the truck..

any remote tuners anyone can suggest?

2017 5.3 silverado

 

I've hear blackbear is a good tune, although I've never used them... I've used tuned by frost on my older silverado and it was flawless, both with my Ls1 s-10 and 2008 RCSB silverad.

 

Not blackbear if you value your vehicle and time. Get a custom tune done by a local shop.

 

Cai is a waste because the supercharger comes with itd own tube and utilizes the oem airbox

 

I went ahead and just bought the diablo i2 so I can throw on the long tubes.. will just resell it later.

I got the CAI for free.. its the GM one.. I work for a gm dealership..
