Default Map 5 without Intercooler fine? - 11-03-2015, 12:25 PM

Hi,
I have a DP, CP and the JB4. I'm driving Map2 and its fine. But I want a little more Power.
Can I run Map5? Or do I need an Intercooler or something special?

Best Regards

I always liked map 2 more than map 5. Map 2 should yield better results unless you are running some decent meth. Then if you want more power you need turbo upgrade and/or meth injection system.

There are new safety features for the meth that should allow meth on all maps, I believe.

I think that is applicable to us as well.

Either way, I would run map 5 only with meth. Or a defined map 6 based on logs. Map 5 is buggy and doesnt work for many people. You want more power go map 6 + e85, map 3 and adjust additive based on logs and octane. Or upgrade turbo.

Map 5 produces the best results for me and many people. No meth.

I run 91 Octane, I can't get 93 here. I run Map5 with K&N drop in filter (yes it is a nice improvement), ETS charge pipe, VRSF 5" Stepped FMIC, Maddad Midpipes and AA GEN 1 Axle back... And I have no issues and the power is awesome!! Way better than Map 1... And it pulls very hard and strong.
I probably would not run Map5 without an IC. Many have said its best not to. But FMIC are easy to install.. And if you get a VRSF one it is only $480, well worth it!

LOL running map5 with no upgraded intercooler is fine. I've been running e40 down ***** bms intake for 15k miles, no problem.

My VRSF 7" was a downgrade due to much worse throttle response. In addition to the added FMIC volume, it's possible there was a leak somewhere since the silicon couplers are very difficult to access, but I couldn't find one using the usual bubble method. Plus, the T-Bolts they included were 1/4" too short to clamp over the coupler thickness. There is also a decent amount of modification required behind the lower grille and to the main attachment bolts. The VRSF FMIC itself was gorgeous, so gorgeous it weighed 20 pounds vs BMW's 4 pound piece of crap. It adds a bit of weight to the chin.

So I sold it and bought a drop-in 5" Mishimoto FMIC with quick connects. It still took an hour line up and click, as the angles were about 1/8th" off for my car and BMW's piping is so cheap and thin it is easy to tear or kink with one wrong move. The Mishimoto is definitely air tight as throttle response seems slightly better than stock, but I really don't feel much of a power gain, maybe a little extra spunk here and there. It's tough to say since FMICs are supposed to add nothing, just lose less when things heat up.

One thing is for sure, the OEM BMW FMIC is a tiny tin and plastic POS. Just another embarrassing, terrible quality part I've pulled out of this car.

At any rate, spend a little more for an FMIC with the quick connects, it's well worth the extra money.

If your IAT are good with stock IC then its a waste of money to upgrade. I would not upgrade unless I see +120F IAT's.
