Re: GIAC X+ and mileage ? (papaTDI)

does the GIAC X+ get installed with the "touchless" flashloader , or on the actual ECU via a chip (hardware) ?

They hook up a cable to your ODBII port and re-program your ECU, no disassembling or removing anything.
Regardless of which tuner you choose whether it be APR, GIAC, Revo, or another--mileage should be exactly the same as stock if you drive it like a grandma since really no boost is being applied.
I run GIAC X+ and I usually average close to 20MPG, just shy of 300 miles per tank. I decidedly do not drive like a grandma, and I'm stuck in traffic or at a stop light 50% of the time which kills mileage just as bad or worse than my lead foot. On longer highway trips when I'm shooting for good mileage, I easily get over 30MPG.
