Hey guys, I'm wanting to tune my pickup, just a simple plug and play in my 2013 Silverado 6.2. I've read a lot about the Diablo predator being good, but do they even make it anymore? All o find on Diablo's website is the inTune i2 and I'm read some pretty nasty reviews of it (on Amazon anyway, so take it for what it's worth) and I'm just wondering if anyone has any experience in this matter?
