Ok I might be crazy but, since the Jb+ works on the MAF sensor and the race chip works on 2 other sensors ( assume MAP) can you run them in tandem or is there any risk??!!

 

Definitely, positively, absolutely don't run them in tandem unless they are specifically tuned to do so.

 

I am planning to run the sprint booster in tandem with the Jb+ though this should be fine

 

Update... Jb+ and sprint booster in tandem!! Holy $&@$..
The car pulls almost too hard for my needs and when is sport mode I can't believe this is my mini!!!

 

JB and SB is fine, some of customers do Manic and SB. I would not do two tunes together. After doing an ECU flash, I got rid of my SB, made driving a manual in parking lots horrible

MAP sensor attenuation does not work on the platform. That RaceChip won't do a thing for you on this platform JB+ on or not.

 

Then how does the race chip work on the N18?? It's not very clear on their website but it says it hooks up to 2 sensors one right before the manifold and another one!!

 

Honestly now with the SB I can't handle anymore power

 

It just doesn't add any power. RC is a generic analog only module they fit to every turbo model under the sun. That tuning technique works on some vehicles and not on others. They don't bother to determine the difference.
