Question on BMS Powerbox and Sprint Booster.

Dark_Knight_335 · 05-15-2010, 01:45 PM

So I got my BMS Powerbox installed this morning at AKMotorwerk in Hillsborough NJ. GREAT tune, thanks to all who sold me on it. Question is though, I also left my Sprint Booster wire on as well. Am I potentially hurting or helping the tune in any way? Or is it simply overriding the SB? Please let me know your take- not sure if I should take it off and sell it, or keep it on there

theres been a lot of discussion on this here and there. never really came to a consensus, but from what I remember one would override the other... but thats what people "thought"... no one has actually ever tried it. so maybe it helps? I simply do not know for I have never tried it.

The PBX does the same thing as the SB as well as more, so.... Probably best to just sell the sprint booster.

Yeap, just take it off and sell it. Btw do you feel any difference btwn sprintbooster and pbx?

I would take it off. I am not 100% sure but I think they are additive so you would get some weird throttle issues on map3 with the SB on as well.

I had a local customer with a SB on his car and he switched to the PBX and he said he liked the throttle mapping on the PBX much more, so I would definitely get rid of the SB and get some money into you mod budget
