Hennessey Tune

Has anyone tried the hennessey tune? You send in you computer (brain) they tune it and send it back for about $500.00. Wondering what power gains you get.

I know quite a few people here in the area that have the HPE tune and are very happy with it. If you have an Auto I'd inquire about TCM also, otherwise you are good to go. I raced one at the track and he beat me every time.

I get full dyno tunes from a guy that has been tuning LSx cars since the early 00's for $400, most shops charge between $400 to $550 for a true dyno tune. IMHO $500 for a canned tune is a ripoff. Every car is different, if I was you I would call these guys & get a quote from them, they've already tuned many high HP 5th gens & have a rep that is as good as anyone's.
