Holy cow. That is expensive! You can get it on ebay for like 40 bucks or less. It's going to be basically the same thing. Actually there was a post somewhere that shows you how to make your own too. I just bought mine on ebay from Checkered Motorsports or something like that.Thanks ...i think the shop i was gonna get it from it was about $70 for it
its a timing retard eliminator. you plug it in and it tricks youre ecm into thinking its in fifth gear eliminating top speed limiter and running a more advanced timing map. do a search tons of crap should come up about it. when i had it on my tl i didnt notice a difference but other people have claimed improvements. cheap mod to do.I hate having to be the one to ask the question.... but... what is a TRE?
