I want to buy a good budget tuner for improved mpg....which is a better choice?
06' GMC 3500 SLT 4x4 CC DRW, Air Raid intake, 4" MBRP catback, DS Predator 85hp tune, Engine Runup water injection, bilstien shocks, soon to have Qudzilla XZT. I tow 34' HR 5th wheel 14,000 lb GTW. DS throws high EGT's so i'll try XZT to keep EGT's down and MPG up. we'll see? Any info on stacking?LWATSON;1585455; said:Erkius fill out your signature so we'll no what year D-max you had your Predator in.
I had HT on my 04 LB7. Good power, reliable but no improvement on MPG to speek of.03LB-7dmax;1585123; said:It dont, but predator will give better mpg, than Hypertech, Cuz hypertech uses part throttle fueling, and realy wont see a difference.
