Re: speed booster a must read
The Sprint Booster is just a simple signal amplifier - much like the amplifier installed in our Infinity Sound System between the stereo and speakers.
You still control the volume by tuning the **** - the amp just increases the stereo's gain by X amount - of course turning the stereo to the max might blow out the speakers.
The SB is the same concept - except our ECU will only send something like a 4.6V maximum signal to the throttle position sensor to reach WOT.
So with a SB installed; even though you still have over 1/4 of pedal travel left, the ECU has reached the 4.6V threshold and the TB is now at WOT - so the remaining amplified signal from the SB is just ignored by the ECU giving the driver a "dead pedal" effect.
To many owners that feels like eliminating throttle lag and seems give their car a "peppy" feel to it and they love that -
For me it's about value - paying $300 for $20 worth of components that takes about an hour labor to assemble and test that doesn't make my car faster is not worth it. - But I just might build my own that will amplify both pedal signals separately (the SB does not) and add a variable gain switch.......
