i have a stock 5.3, and may be buying a mangancharger radix 112 form a friend who is also running this on a 5.3. his truck however has ls3 cam and lifters, if i were to use his tune on my truck would there be anything that could go wrong? we were planning on leaving the stock rev limiter on my truck bc his is at 7k and im pretty sure the stock lifter wont handle that, also the tune is semi-mild being only 6-6.5 psi...any input would be appreciated.
