Awesome numbers Ken. I don't care if they tested it on a one wheel dyno as long as the before and after utilize the same procedure, you have an accurate measure of the gains produced.
I posted the numbers from DTE. I was searching around for someone to do the install and I was going to have them do my Z06 until it started burning oil. I since sold that and have the H2 but miss the power. Regardless of who is doing what they're both respectable numbers/establishments...always more than one way to skin a cat I suppose. You do have almost 50lbs more torque though. Also variables with dynoes can play a role. DTE quoted me a 0-60 time with a stock motor/tranny (Shift kit only)of 6.8 seconds so you're much better than that. HE also said when he was logging the truck he reached 123mph but it was REALLY windy
While there are pros and cons to both places, do you think you'd have a better resale value with Lingenfelter's name attached to the install? I know mods like that don't increase value at all but to the right person.....
