I'm looking to buy a 335i (sport package) coupe next fall, and doing my homework ahead of time for performance mods. I wanted feedback from people here with Juice Box (stage 1) or stage 2, for reliability.
How many miles have you put on (after Juice Box installation)? etc.

Any overheating issues (owners with stock oil coolers) ?

Thanks !!!! :)

2007 E93 335i. I've had the JBS2 on for over 2,500 miles of mixed driving. Drag Strip, Open Track Day Road Course, Mountain Runs, Daily Driving & one Trip to Savannah & back from Atlanta, over 400 miles roundtrip w/ 27.5 MPG Cruising at 90+mph! No CEL Codes, No Problems, except for turning my E93 from a Cruiser to a Cruise Missile!

There are quite a few Stage 1 customers with 10k miles already!

I have a Stage 1 and it is great.
Simple to install and a noticeable power boost.

The only downside is a noticeable drop in MPG. I have been lead-footing it lately to enjoy the new boost, but even driving conservatively I'm down about 1.5-2 MPG on averge.

This is something that I am worried about. My car is my DD and I really don't want a drop in gas mileage since I am only averaging about 18 or so mpg.

As long as you drive it normally the MPG will stay the same, but with 20-40rwhp more on tap (depending on stage), it's a lot more rewarding to floor it... :rofl:

:bigpimp: That was the part that I was worried about, but I would never floor-it :angel:

Update:
My mileage is starting to creep back up to normal 1 week after installing the stage 1. I think my lead footing it was the real culprit. I'm still a little below where I was (~1MPG lower), but let's give it another week and see.

I do love my JB Stage 1!!! Thanks Terry!
