JB+ Quick Install = :)

Picked up the juicebox plus quick install for the 335i. Installation is gonna be a pain because of the filter box and intake in the way unless you break the clip then it only takes like a min to install.. so give yourself 5-10 mins to attempt it then you may decide to just break the clip, which should be fine anyway because friction should hold it in place.

Took it out right away for a quick spin and WOW! the car just keeps wanting to pull from 2nd to 3rd to 4th gear.. Drove it to a road along an airport runway which was about 1.5 miles straight away.. I could definitely tell the diff in boost and power immediately.. I had the default setting of +2.75 psi which was suppose to add 40hp and 50tq to the wheels.. Not sure how much hp i got or tq but man it goes fastttttttt!!! Hit about 130 and i decided i should be going that fast in broad daylight..

Definitely worth every penny.. for 3 bills, the car that much faster..

me = very satisfied!

JB plus = worth it!

You should definitely replace the clip. Dealers are on the look out for tunes especially if you end up going in there with a HPFP failure.

Interesting.
How many psi can the JB+ max give?

+ what octane will it need at max psi?

Cheers

Terry should chime in but I believe that on 100% it is 5 psi above norm.

Dyno shows about a 70rwhp increase on 93 octane at 100% setting.

A lot of bang for the buck but at 100% you want to be wary of throwing tuner codes so you will need to get them cleared before going to the dealer.

Thank you SteveMD.

And not another intercooler or downpipes required. And a BT tool is all needed to erase codes so nothing reveals itself at any service or warranty job. Fool proof eh?

Again, Terry would be the man to answer but no, nothing else required. Clear the codes with a BT tool or go to your local independant BMW mechanic who may have one.
