WILL THE 2000 1 TON DULLY I HAVE STILL PASS CAL SMOG WITH THIS TUNE UP EMC ( RON RAINES, 07/16/2019 )

Yes, you will still pass emissions as long as you don't tamper with the existing emissions systems.

1996 c3500 dually 7.4 with 5 speed. Would you be able to tune this on a new computer so I can keep the original? What type of gains could I expect with a tune for this? ( Luke, 06/03/2019 )

If you choose the core option we will program an ECM here and ship to you. You will gain approximately 35-40 horsepower and 45 lb-ft torque.

I’m interested to know if you change the shift points or anything like that cause I have a shift kit in the transmission already. ( 06/02/2019 )

Yes we modify the shift patterns to hold the upper gears longer, your shift kit would not interfere or cause issues.

Hello I have 2000 GMC k3500 Truck. I do some pulling but mainly driving with this truck I have a factory y pipe with no cats and dual 3 inch flowmaster mufflers. And a k and n filter. Truck runs great doesn’t miss or anything just seems to not really have any power at all in 1st gear and alittle more in second gear. I heard these trucks have a torque management system does this computer give my truck back all it’s power? and will it improve my over all power? ( Beau , 05/26/2019 )

Yes you are correct that there is torque management which "pulls" back power when taking off from a stop. We modify this so that it is still "safe" but definitely wakes the truck up. This is only 1 of the many changes that we make with our programming to achieve great power gains.

Do you have any videos of how to locate and remove my ECM? I have a 1999 Fleetwood Flair with a 7.4 Workhorse. ( Keith Sanders, 04/19/2019 )

No videos but your ECM is fairly easy to identify and replace. It is located on top of the radiator support and has 4 connectors going into the back of it.
