well i know i just got a little ole 4.8L 4x4. but let me tell you. i put my nelson tune in yesterday and WOW! thats all i can say. man that allen nelson can sure tune a pcm. man the truck feels so awesome. i mena he really made my truck fun to drive. it is one sweet machine now. he has great customer service and second to none in quality. thanks a millon allen.,

 

i was gonna post for ya but didnt know if you wanted to let your secrets out lol..

ill say this, the lil 4.8 use to be about 1.5 trucks behind my 5.3. now we are dead even then you start to pull on my around 75? He woke the truck up definitly! Props to allen!

 

Congrats on the tune. Another satisfied customer. Nelson performance

Congrats Larry, on the tune, and cracking HD.

Bruce

 

thanks bruce, it was great seeing his face. lol

 

I just had a custom tune done on my 4.8L also by Synergy Motorsports and man you ain't kidding. I swear it feels like I just added a shot of nitrous when you go to pass someone on the freeway!

I'll never doubt the benifit of a custom tune on a stock truck again.

 

man mine feels the same way. its so unbeliavable. just plan wicked.

 

Not to hijack this thread, but i just put my nelson tune in yesterday as well. SHifts are way firmer, and it just pulls and pulls in second gear now. Im gonna take it on the highway tonight and test her out.

 

Damn I need one.
