WOW
Great review!!! I was on debating between the Procede and JB4, but you definitely made that decision much easier.

Nice detailed review. What meth mixture and additive are you using? What size nozzles? I ran 91 octane, dual meth nozzles with a 60 additive (perhaps not recommended), but the car definitely kicked ass. On my JB4, if I trapped 124.0 mph on the Vbox I thought that was a bad run, lol.
Here is one of my 125.3 mph runs with the stock rear catback. (I got 126mph with a custom rear exhaust). Any time you can get under a 8.0 sec 0-100mph, or a 11.7 sec ET with a mediocre 2.0 sec 60' on stock turbos, your car is running strong!

I'd like to maybe try a single cm3 tapped into my Stett CAI, even though it would evaporate before it reaches the engine, I would think it'd help to help cool things off even more!

ahhh......i was unaware of this, so it just makes everything smoother int he powerband...? I know it has all kinds of other features, but i assumed there was a little bit more power squeezed out of it.

The JB4 is generally much more powerful than the JB3 during normal driving conditions. Only the race gas maps are similar in power which is limited by the turbos. But, the JB3 is no longer compatible with BMW's newer DME versions anyway so using it isn't really an option.

Very true.....the JB3 was very raw and punchy.....the JB4 is smooth and refined....and more powerful. Like a fine wine, it gets better with age.

Just an update... The JB4 is still performing awesome and I'm very happy with the way its running. I changed my lagfix setting from 80 to 50 and its even smoother now, its not so touchy/boost happy while driving around town, the boost just comes on smooth as you apply more throttle, just the way I like it!
And now for the best part... At my last fill up, after the gas light turned on, I added 11 gallons of pump 93 and 3 gallons of E85... Lets just say, this thing is a beast now! I couldn't believe how much the car like it, and it even feels like it runs smoother. Map 5 almost feels like Im running the meth injection, and then Map 3 with the meth injection running a 70/30 mix and additive set at 50, is just crazy!! I'm definitely hooked on doing the E85 mix now, and I can't wait to get to the drag strip!

The JB4 isn't that hard to do though, it should be easy for most people, especially with the good instructions and support you get from them!
