2003 Silverado 2500 HD, exhaust and a UPD intake. Factory 4.10's.

Will the Hypertech give me anymore power? Is it a worthwhile modification?

 

If you truck is a durmax theres a stage 3 .. Yu can up it to 95hp... Look on ebay yu can find a used one there cheap.... \

Forgot to mention, the motor is the 6.0L.

 

Get a Wester's or Nelson's tuned PCM, they'll make way more difference then the hypertech. if you use the truck to tow your car, Wester's can make you a program to improve it's towing ability (Nelsons probably does too, but I don't know for sure). Tbryne motorsports is holding a group buy on right now for the Wester's, good until the 20th of Feb. Link for Wester's is in my sig

Spend the money on a Nelson tune. Trust me, its like night and day.

 

I had the same question about 6.0 hd? I just want some hard #'s 1/4 times and dyno #'s.

 

My Gtech times dropped .5sec with a Nelson tune. Waaaayyyyy better then the supercraps tuner that came with the magnacharger.

 

L82 is your Nelson tune a mail order or driven tune?
