Can anyone confirm if this works?
I dont care about doing 150 down the road. I only have the 528 2010
but the throttle response sucks. Does sprint booster really make a difference?
Or is there a better way?

a quick search should get you a few threads on this subject as it's been discussed often in the past..

in short: yes it does work to increase your throttle response. it doesn't really increase performance persay, just feel....

Ok Thank you.. yea preformance is not my concern. don't wanna get into that financial mess lol
Just the take off response. Thanks again.

aside from sprint booster, the velocity throttle controller is another device used to increase throttle response..the main difference is the velocity has different settings so you can select the sensivity of the throttle....

pics don't seem to work but the info posted is good..

I have same question about "making 528 a bit quicker". Cannot decide between Sprint Booster and BMS Power Box. What you guys advice?
