Check it out! On ebay you can get it for like $800 instead of the usual $900. Strongly recommend it.

I personally run the JB4 tune and love it. You can purchase the tunes used with no problems, however make sure if you buy a procede used it isn't VIN locked.

Next, do Downpipes or FMIC. I reccomend FMIC first in a hot climate. Catless downpipes remove the exhaust restriction (primary cats), and help your turbo's breath better as well as reduce backpressure/heat. Claims of up to 20whp are possible if tuned. I would buy DP's used, as it's just piping.
-AR design (Fit great, high quality welds, most expensive. My reccomendation)
-VRSF ("Knockoff" AR's. Alot of people have had success with them, but all of my local installers told me they have had fitment issues)
-AA, Macht Schnell (Both high quality options that fit great)

FMIC:
You have a number of choices and can't go wrong with whatever you choose. I personally reccomend the ETS and AA FMIC's. Go with an FMIC that replaces all of the factory plumbing, because you don't want to retain the rubber and plastic restrictive piping.

Intake:
The stock intake with a drop-in filter is a great choice if you plan on keeping the boost at around 13psi (Stage 1/Map 1 on the tunes). Otherwise, I would go with a dual cone intake (Vishnu/BMS/AFE/CPE), all the same basically)

At this point you are FBO (Full bolt on). You can get an upgraded charge pipe, diverter or blow off valves, as well as exhaust after FBO, but it isn't really required and won't net you any performance gain. Let me know if you need any more help.

I then installed a burger motorsports cai and oil catch can to keep oil out of my new intercooler. Ran for another week, again to make sure no problems. Then came the jb4. Installed and ran map 1 for a few days. Set it to clear codes mode, then installed the down pipes and billy boat exhaust. I have been running this set up a couple weeks and everything works great together. I am staying on map one and running 20 degrees cooler, on avg. The reason i did it in steps is so if i had any problems, i could narrow it down quickly. The only hiccup i have had is that on map 0 i seem to get a ses light every once in a while. So for now i am staying on map 1 and with no problems.

Cobb A/P: you can get a Pro-tune if you want to incorporate meth
FMIC: I'll add Forge motorsport to the list. Absolutely no trimming and very good quality.
Intake: I'll add Injen DCI to the list, the sounds great.

Note...you may want to change the DV's and charge pipe since you will be at a higher boost level. I'd recommend Forge DV's, great quality and the ER charge pipe.

Limited slip differential (LSD) first. Get the power you already have put down to the ground more effectively, keep the car from using your brakes and cutting power to pretend it has an LSD (note this happens even with DTC/DSC completely turned off). Then do the power and other suspension mods.

1. LSD (quaife or wavetrack, will cost you about $2500 for an already-built pumpkin with either in it from VAC, install about $500 or do yourself).
2. Cobb (watch the private sellers here, and pick up a used one for $650, maybe even less)
3. Other suspension/brakes. With a real LSD, you can run M3 bits, including the M sway bar, busings, arms, etc, in back (sway is only suggested if you have the LSD, others you can do without). Coilovers, and then corner weight the car.
4. Bigger brakes to bleed off the the increased power you have (and will add).
5. Bolt-ons (FMIC, DPs, etc).

Intake: BMS Dual Cones $100 new
Meth: You'll have to find out yourself on the tune you choose $450-600

That should be close to $2500 or around 2000 if you skip meth.

Power is fun, but it stinks that BMW doesn't put an LSD in anything but M class cars anymore...open differential, using your brakes and limiting throttle to pretend there is an LSD there to limit wheel slip. More power = more wheel slip = more power lost.

I have had the VRSF 7" fmic for about a month and i love it. I have their catless dp's too. I run a JB4 tune on either map 2 or map 5 with 93 octane. Map 2 seems to have a little bit more power/better performance.

There are a bunch of intakes and some of them are pretty expensive. The BMS dci costs $100 and performs equally well. After researching them extensively, I concluded that the only reason to buy the more expensive ones is if you think they look cooler under the hood.

Once you're FBO, spend a 180$ for a FBO + E85 pro tune by PTF.

okay guys since i wrote this thread i made to stage 2+ with cobb tune.
