JB4 question

SaMaster14 · 06-11-2013, 07:04 PM

I have a 335is and am looking into picking up a JB4.

I use 91 gas mostly all of the time stock.

I would most likely only run map1 or the economy map (turbos off) otherwise Ill be running stock most of the time.

Since I have the is, is it necessary to go with the DCI as well, or will my stock parts be able to handle the JB4 pretty well?

Also, does anyone know of any authorized dealers, or should I just order via the website?

Best,
Sam

No you don't really need the DCI intake. I have the stock intake with just a drop-in filter,and I'm on map 2 with 93 oct gas. You can definitely feel the HP differences. I moved up from JB+ and I like JB4 so far.

Oh BTW order for Mike@n54tuning.com. It's free shipping so it will be around $20 cheaper.

No you don't need the intake. @Jeff@TopGearSolutions will set you up. On 91ACN I highly reccomend COBB, however, especially with a DCT trans (You will want true load reported to the TCU as to increase line pressure and prevent clutch slippage.)
