Our tunes are regarded as the best you can get. the Super 60 Super 54 here or a stock GM turbo. Although we can have tunes made for most any combo of other brand turbo or power adders.
For OBDI (1994 1995) vehicles you will be mailed a new EPROM chip. Simply plug it in and done. The nice thing about OBDI is you can change tunes quickly.
For OBDII (1996-2000) vehicles you will need to send in a ECM to be reflashed. I recommend you supply us a good spare ECM and keep your original. Any ECM from any “diesel” Suburban or truck from a 1996-2000 will work on OBDII.
ALL TUNES HAVE A LEAD TIME OF 3-4 weeks FROM THE TIME YOUR ECM IS RECEIVED HERE.
For all tunes you need to email all the specifics on your truck like Vin #, 2WD or 4×4, what turbo, manual or auto, gear ratio and any other power adder or any other pertinent info. On OBDI I need the # off your injection pump and/or the code on your stock EPROM chip (inside ECM).
Here is is what OBDI ECM looks like. They are all located behind glove box in truck and Suburban. Notice the removable EPROM (blue chip). OBDII has a solid box with no access lid.
