As you know our 535i is little heavy.
So if I install the JB4 , I would leave it on map 1 or map 5 (auto tuning)
For horse power , it is little more than BMS stage one right.
Is our stock boost like around 8psi or something. Map 1 will get it to like 12psi?
How do you like it so far? The Bluetooth is nice but additional $140 lol.
Thx

Hey Ced! Perfect timing that we both have the same car and both getting the JB4 done lol! I will say at least for me the throttle response is much better. But every driver is different so we may throttle differently if that makes sense. I wanna say you can still use your Sprint Booster but double check.
So Map 1 is pretty much the same as BMS tuning. But Map 5 ranges anywhere from 12-17 psi depending on your octane (I use 93), conditions and modifications. Even if you're stock from what I was told.
Our stock boost I believe is 7psi. I'll double check on that. So if you're using map 1 that's 4.5psi over so you'll be at 11.5psi.
So far I'm happy with the power. I'll be even more happy once I put the catless downpipes, charge pipes and intakes. Will I ever go BM3? Maybe but for now this will suffice. I no longer crave for the crazy power like I use to when I was younger. I only drive my car on the Weekends or when we go to the car shows and local cruises. She's not my daily driver. I will get the Bluetooth because I do wanna monitor boost, temperatures, ect so that's a nice feature to have
