Has anybody had any experiences (negative or positive) with changing the ECU chip to a performance chip? I tow a trailer with my 2008 4.0l 2 wd Frontier crew cab, and could use better power and fuel economy while towing. Specifically, will a new chip viod my warrenty or cause ill effects to my engine? I have 35K miloes on this truck, and was hoping for better gas mileage than the 15/19 I get now.

Thanks!
