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.

My two cents

Reviewed By Braden W (BELLEVUE, NE) Reviewed for a 2003 Chevy Tahoe —6/5/2013 8:43 AM

Currently using the regular gas tune running 89 octane. Noticed more power than running stock with 89 octane. Moving acceleration increased quite a bit but I haven't noticed anything off the line but my truck was already peppy in 1st w/3.73 gears. Highway above 55mph i have noticed roughly 5mpg better mileage and city driving 45mph and under its about the same or worse mpg probably because its kicking in more fuel. Currently watching intake temp vs outside to see if a CAI is colder!
