So to start off I have a 2017 Silverado 1500 crew cab short box. Has about 44k in miles new torque converter at 27k. just recently put a leveling kit on 2in in fron and 2 in the rear with 285/65/18 fallen wild peaks with .25in spacers on all 4 tires. Also put k&n CAI and a rough country dual exhaust. And a range afm delete. And I’m very happy with everything I crept now with the heavier tires it’s quite sluggish than before. I just ordered the super chip flashpaq thing and I don’t wanna do anything custom or extreme but I want to wake the beast up some. does anyone have any experience with this tuner? I’m not trying to be a corvette n a drag strip but just want to open it up some and hopefully somehow help with the crappy shifting. eith the afm delete alone helped tremendously. and also is it possible to still use the range device if I don’t have the tuner turn it off? I’m very new to tuning etc so I’m not trying to get to crazy without guidance.
