Max Energy Talk - Tahoe 2003

Reviewed By Barron H (SAN ANTONIO, TX) Reviewed for a 2003 Chevy Tahoe —8/11/2017 8:15 AM

Great product- we lifted our 4x4 by 6.5" and need some extra horse power to compensate for the extra weight. Max Energy did the trick. Added 56 horse and brought the old Tahoe back to life. It now has great passing power and burns rubber from a dead start.

Bully Dog BDX Tuner Reviews


IT WORKS!!!

Reviewed By Chad H (Bivins, TX) Reviewed for a 2012 Toyota Tundra —7/25/2017 8:36 PM

Very easy to use. Just follow the directions. Received the BullyDog BDX one evening and had my truck programmed the same evening. There are several settings. I only chose a couple to begin with, but noticed the extra power immediately. Ibis will it set in economy right now, but I haven't noticed a tremendous increase in mpg yet. I mainly got it for towing my camper which is 37' bumper pull and weighs 8800 pounds in the dry. So far, I am very pleased with the BDX.
