Hi folks,

I am a complete newbie to the JB4. Have heard a lot of good stuff and have the following Setup. I regularly track my M5 F10 and do a decent amount of spirited driving.

Current Mods -

1. 300 cel Catted headers
2. Titanium Series Akrapovic Exhaust
3. SSP DCT Cooling Kit
4. Eventuri Intakes
5. BPM Tune

Car with stock turbos without clutch slipping pulls 620 whp on the dyno

Next Mods -

1. SsP clutch R (900)
2. Stage 1 Pure Turbos
3. JB4 + BCM + Meth

When I spoke to my tuner he said that the additional power can be gained via the JB4 and adjusting the parameters directly on the base map. I also read Terry writing this somewhere.

My question is :

1. The JB4 has preset maps from what I read ? How do these maps
Work in tandem with the ECU tune that I already have ?
2. With standard pump gas 93 Octane, what kind of power and boost setting are available to be made ( I may have missed this somewhere)
3. For really getting the best out of the car with a relative focus on Safety, how does one adjust the boost etc without fear of blowing the motor (I did read that there is a safety built in, but just to make sure)

Any advise here is helpful guys,

Thanks a lot in advance

1- Works the same, just click what map you want at what boost level.
2- Would need a log on map 0 to evaluate and see how much more we can push it on 93 only with flash+JB4
3- You would use the methanol map with the added safety features if you're pushing it. All other maps have safety systems as well.
