Flashpak Tuner

Hey, I'm curious if any of you folks have used a Flashpak Tuner? I've thought about trying one many times, but never have. My WK is a 2007 with a 4.7, and it is a daily driver 98% of the time. I never go off road, but pull a 2000 lb. bass boat occasionally. Would one of these really help? I'd be looking for better gas mileage more than anything else. Just curious what your experience is on these. Thanks for any replies!

I use one but not for mileage I use it for HP. Trying to get better mileage out of these bricks is kinda pointless they are a heavy brick rolling down the road

Totally agree with the mpg, waste of time really as I gained maybe like 1-2 miles with the 91 tune. But the power difference is night and day, and I really wanted it to calibrate the speedo with the difference in tires

If you get one (and you will like it) don't get the old model 3872. The new model 3874 has just been introduced and it features a color high res screen vs the old, small black and white display. PM me if I can be of assistance - I have them on intro special now
