i think the hypertech is a good choice its not price has 3 levels and you can tow on all 3 levels
i just got efilive in my truck and i love it. its the best chip u can get for the new lmm but with any chip u have to take the exhaust off. and get new on it b/c if u dont it will plug up the stock crap, and it will run bad and get worse mpg. i got a tune of 150 in my truck little smoke if u floor it but then it stops.
