I have Racechip ultimate on N63 for 2 years now and no issues. The new one looks promising
I never dyno mine but the gain is definitely higher the JB4, the basic one. I had both

whats the specs for the RC ultimate? They just recently came out with this GTS Black so I am guessing it has more power and it even says 7 maps.

RC ultimate has different dials which has almost 15 setups but probably 5 are usable. I believe the new black model can be adjusted without open the module Like the ultimate. As for the gain, I am not sure. Their US site should still have the specs for ultimate.

thats about right. With the use of the app they can change the map setting based on customers taste. like download and flash? i hope. I just ordered it and well see the difference. Had the jb4 beta before but did not install bcm coz of other members saying it max out trims using e85 and one having thrown rods. lol!

Dunno if he made a thread about it but he messages me saying that he sold the jb4 that he bought from to fund the repairs then bought a new one.
