Tuners

[hoopaugh15]

I'm new here so please no criticism but I have a 2013 c1500 w/t truck with the 4.3 4l60e and 3.23 gear 265/65/18 tires... I need a tune to open this guy up what is a good tune and where do I get it????? And any other tricks to modify this guy would be nice

Ur best bet would be a 4.10 gear set for lower end power and a shift kit for the 4L60 but that’s a fleet service powertrain you aren’t going to get any worthwhile power out of it unfortunately. You can tune some of the torque management out of it but at that point you’d be 2k into a truck that’s still noticeably slower then a stock 5.3 [emoji2369]

My buddy has a 2011 gmc with the same engine trans and rear gear and it runs really strong the engine revs up faster and it's really strong when you drive it makes mine perform like a 4 cylinder..any thoughts
