What are the best mods to add power? Is there a chip or tune that is better to get? How much will they add?

Hi, I'm the search function, have we met? lol, just kidding...but search for JB4. Best horsepower:dollar ratio out there for the F10.

I just installed my JB4 last weekend. Have been time traveling ever since.

"up to 60whp range with the n63tu motor." http://www.burgertuning.com/N63_Jb_B...nce_Tuner.html

If you want larger gains with a more reliable ECU flash, I recommend DME Tuning. Their Stage 1 was dyno'd with 130whp/140wtq gains. www.instagram.com/DMETuning let em know TheBlackGT sent you and they'll take care of you.

JB stage 1 - adds 30-40hp and another 20hp on racegas (N63) N63TU (60whp)
JB4 - N63: depends on which map, Map 1 is equal to JB stage 1 (~420whp), Map 2 is equal to the old BMS JB Stage 2 (~440whp), MAP 7 w/BCM is ~500whp
N63tu, all the above plus N20/M5 TMAP sensors, (~550+ whp)

Badblack550/BPC/Gintani/Mission Performance, etc does Flash tunes.

Badblack550 sells the N63 Cold Air Intake, not sure how much power they add, but it's a question he could answer.

Down pipes add some good power, I heard about 20whp

I dont think a catback/resonator delete adds any power.

My F10 550i xdrive (N63TU) is tuned by DME tuning, gains of 145whp/150wtq. The car is a monster after the tune, I highly recommend them.

Off the shelf, Jb4 or Active Autowerke OBD flash will offer the most power.

Thank you for all the info guys. I'm in Oregon so the DME Tuning in NJ tune isn't practical. I'll check out the JB4.
