Dear Auto Enthusiast. Flashpaq delivers features you expect from Superchips, and some not found in competing. Manual Transmission Skip Shift - Chevrolet cars. Installed a Superchips Flashpaq in my 07 Classic 2500HD last week and I was pretty impressed with the difference it made in my truck. Now I know there will.

I purchased a Superchips Flashpaq 1805 Tuner for my 250 two weeks ago. I loaded the economy program into the truck at the dealer and really liked what I felt. Quicker throttle response, better acceleration, but really not a good chance yet to check my fuel mileage. We're heading to the beach in two weeks so that'll be a perfect test to see if it'll exceed my typical 17mpg highway (on a good day). Earlier this week, I changed to the 'tow' mode since I was going to be hauling trailer loads of pine straw for my landscape business. Today as well, I had to haul my tractor to the dealer for service and this is where I'm curious as to what is going on with the truck.

What I 'feel' with the truck is slower shifts with the transmission. When moving up through the gears, they just don't 'grab' the next gear as quick as they used to. Single Collection Hotchpotch Rare.

Also today, when I was driving down a slight grade with just a little bit of throttle, the engine 'skipped' three times within about 15 seconds. I'm not saying this is definitely the tuner, but after 26,000 stock miles, it's never done this before. Any suggestions or comments? Hp Me10.
