I haven’t done the test, but I did feel more of a ‘throw back into your seat’ with the brake boosting. There’s a benefit.
Also, not sure exactly how that say it, but I don’t feel significant improvement at partial throttle, but certainly at full throttle, over stock.
Debating what’s the next right mod, intake or catted downpipes.

Damn! What all do you have done to yours? I have an MST CAI, Burger Pedal Tuner and the JB4. I dont have Launch Control, but Im going to try some Brake Boosting tomorrow if it decided to quit raining for one day this week. Ive never done brake boosting before because all of my cars until have been naturally aspirated, but we shall see I suppose. I too am looking for map 6 numbers. Im running 4 gallons of E85 with 12 gallons of 93 at them moment too.

Our 2021 has significant and noticeable part throttle increases, so much that my wife noticed and didn’t even know I installed/tuned.

It looks like he has a 2015 c400. So no BCM needed for his. If he is running E30, he should be using map 3 or 4 even for most optimal gains, unless timing is being pulled, fueling is off, etc. When using a jb4 soley, many of us have had major fueling issues as we try to push the envelope.

Hey guys. Yep, I’ve got a 2015 C400, running 93 on Map 3. BMS said logs look good, but suggested sticking with Map 3. Suggested E85, and any bolts ons.
