Both of the kits I have found on ebay direct from Magnacharger and Roush. So not just some random company that issn't authorized to be doing it.
Both the maggie and the roush both require the PCM being sent back to their tuners for my 05 application. The maggie does have a handheld option, but its more and with all the complaints I've heard about the tune they give you, just flat out not worth it.
I know that ideally I would want someone able to tune it on a dyno and be right there with the truck, but I don't need perfection and an absolutely perfect A/F curve across the board. Just something that will work and perform well and put down some good numbers and maybe humiliate a few unsuspecting people
