What about transmission shift points?
Except in manual mode, the tuned fattened power band can't be fully utilized without modifying shift points to match the revised power band.
Yeah, the curves look good.We just let it shift itself, makes more power to redline with the JB4 installed as dyno reflects.
That is not bad. 272HP and 365 lbs/ft at the wheels is very impressive. Do you have to drop the front bumper to install?+46hp/68tq To the wheels too
Depends on the size of your hands and your dexterity. If your hands aren’t too meaty, you can do it without dropping the bumper cover. You’ll spend 30 minutes just on the intercooler connection. It’s 95% patience and 5% skill. The remainder of the install takes about 10-15 minutes. I’ve installed/removed it twice now. Worth noting: There’s a small plastic shield that you’ll remove inside the lower grill that you won’t be able to reinstall without taking the bumper cover off.That is not bad. 272HP and 365 lbs/ft at the wheels is very impressive.

They sent the additional harness free of charge, and provided a link on where to install the 2 new pins. Super simple. Probably a 5 minute procedure.For those using JB4 on their M3TH, did you have to send your original harness back to Burger Tuning before they send you the new harness with updated MAF connector, or did they send you the updated harness and asked you to return your old harness.
