BMS Tuning for N63TU engine

RED99HT · 02-03-2014, 08:15 PM

Ive been following several of the threads in regards to the N63TU BMS tune and obviously the power output is very impressive. I have a 14 550 LCI and although the power is very impressive I always crave more. I also enjoy reliability and no headaches with my car. I drive 35k a year and plan on keeping my 550 for 100k + miles. So forgive me with a few elementary questions as this is my 1st turbo powered automobile.

How much boost (PSI) over stock does BMS tune push? And is that at full throttle or is it always pushing X PSI over stock? What I am getting at is if I am cruising down the Hwy at 1800 RPM is the tune smart enough to level out at stock level boost and then when I hammer the throttle it pushes X boost over stock? Is the BMS tune constantly putting excess strain on the power-train at all levels? How are the MPG's effected? Should the tune be taken out when I inspect my car and emissions are scanned?

The threads your following show graphs of boost. Stock and tuned.
If you have done any research on the tune you would know it only effects wide open throttle so gas isn't effected.

These types of questions is the reason I don't log into the forum. No offense.

Well, I guess thx for your response.... My apologies for not knowing how to comprehend a AF ratio chart and asking a simple question...

Not sure about the 650. But if it's a 2014 should be maf, I would check with Terry.

Thanks for reply Man. I think in the 650 it should also be the maf, but it was just too hard to get it unplugged.

Sent them an email asked about the issue.
They told me there will be a black tab on the MAF sensor and I should press it in order to disconnect the MAF.

Can you send me a picture of your engine compartment?
Not sure where is the black tab? Are our engine compartments same?
