Its awesome!!!! Finally, this big truck/small engine combo doesnt feel like a turd anymore! I got the 89/91 tune and had 100% torque management removed and this feels like a different truck! I dont have to put much foot into the throttle to get it moving anymore. This is a 1999 ecsb 4x4 with the little 4.8. Have not tried towing with the new tune yet but so far its so much better. At first i had 60% TM removed and it was better but still sluggish so i ended up needing a retune for some other stuff and decided this time to have 100% tm removed and WOW! Good job to the people at NP!!
