JB2X Install and first impressions

Digital.James · 03-22-2008, 06:36 PM

Just got done installing my JB2X. Install was pretty straight forward and went off without a hitch. Install is pretty much a cross between JB2, H and R. Hardest part was bypassing the boost solenoids, shit was hard to get off.
Few pics:

I used a piece of velcro to mount the X switch on the inside of the fender, so I can pull it out to turn the knob.

Car fired right up with no codes/cels. Went out and filled up the car and put some miles on it. Car pulls pretty hard as it set to 0% on the X switch. Set it to 50% and the power curve seems nice. Made and appointment for a Dynojet this weekend and will post results.

No, I don't think they're on sale yet. I guess I am a tester...

really not a big deal as you need the JB2 to run the X switch. in essence you are only out the $15 you paid for the Hot pill...

Newb here to the 335. I am likely going to be purchasing one this week and already will be getting coil-overs for my first mod along with exhaust and software. Seems there is no clearcut choice for software...either procede or jb2 seems to be the most popular right? What is the cost of each of these and has one shown to be more reliable than the other in terms of no CEL or other problems?

The only software option currently is Dinan. Not sure about reliability but it is the most expensive, but comes with a warranty. Other options are all piggybacks. Plenty of info on them here for the reading
