Ok so my boss just bought a new 6.4 and wants to bump the power up some...between 60-120hp. Whats the best options out there as he wants to retain stock tranny and exhaust system for warranty since our 6.4 work truck has been in the shop 5 times already. MP-8, bullydog, SCT, Spartan...whats the best bang for the buck that'll do the job right?
