holy crap!!! didnt see that lol nevermind hptuners it is haha

But... this is the same MEFI4 that I posted a link to at least 6 months ago. So this one is red and has an MSD sticker on it... it's still the same controller! There are several companies selling this same package. Just do a search for mefi4 and see how many companies show up.

FWIW mefi means "marine electronic fuel injection" and it's built by GM. mefi3 controllers have been used by Harley, and the mefi boxes have been used to tune various GM engines during pre-release testing. Good stuff.
