Rated 5 out of 5 by from Works great I bought the flashcal to correct my speedometer after getting bigger tires. In less than 10 minutes it was corrected and I was back on the road. Definitely going to upgrade it to the flashpaq.

Rated 5 out of 5 by from Great product I bought to recalibrate tire size and disable AFM. Did a great job and plan to upgrade to tuner in the near future!!

Rated 5 out of 5 by from Worth the money I bought this to turn off the afm 4 cyl mode and it did the trick with no complication. Now I can calibrate my tire size when I get bigger tires and clear codes for the same price as the competiors that just turn off afm. I am very happy with this purchase. Wasn’t wanting to tune or add power just couldnt stand the helicopter noise that my exhaust made in 4 cyl mode. This is worth every cent.

Rated 5 out of 5 by from GM 2545 Flash Cal I bought this Flash Cal to update the tire size on my 2015 GMC Sierra 1500 Denali. Worked as described and very easy and quick to install. Got lucky and had a local police department who had a speed limit sign up giving you your speed. It corrected the speedometer to within 1 mph in reference to their speed device. Great product. Will be looking into upgrading to the FlashPaq at some point.

Rated 4 out of 5 by from Excellent Tech support I bought this product two weeks ago to adjust the spedo in my 2006 2500 HD. I had multiple issues with configuration and several error messages not allowing me to make any changes to my truck. After 4 tech support calls I got the correct tire size collaboration for the tires. Tech support was the highlight of the process. Thanks for doing a great job and refusing to give up.

Rated 5 out of 5 by from Works as described Followed the instructions and checked for software updates before plugging into my 2016 Chevy 1500, 5.3L. Programmed the truck for the tire size I have on. Truck shifts much better now. I’ll reprogram when I go to the next tire size. Wish I could use it on my father in laws truck. He runs 35” tires and we drive the same year/model except his is an LTZ 4X4.

Will I be able to change the throttle response on my truck 

Asked by: Jones137
This model is strictly tire height/gear ratio adjustment. This will not offer a throttle response adjustment. Checkout our Ampd throttle booster kits

I would like to limit the speed of our 2007 GMC Denali 1500 to 75MPH. Is this possible with the model 2545?

Asked by: Jeff67
We cannot legally lower the top speed below what the factory has it set to. All we can do is raise it

I have a 2011 Chevrolet Express 3500 (1 ton van) 6.0 liter gas, 6 speed auto. Will the GM truck version of flash cal work for my gear/tire/psi changes I need? If unsure I'd be glad to be a guinea pig!

Asked by: Van Man
Unfortunately it will not. We do not support the express vans. Check with our Sistery company Diablosport

I just bought a new GM/ flash cal  for trucks  Had some help from your support couldn’t figure out how to adjust speed limiter   I noticed when I was setting it up on the computer it told me I could upgrade it for $118 what do I get for that money  Bob

Asked by: Oldforge106
That upgrade would turn the flashcal into a flashpaq. That will allow you to tune the engine/trans to pick up extra power/mpg
