Thank you everyone for the support.

The SB will theoretically increase 0-60 times and passing power due to faster onset of WOT. Expect a tenth or two difference dpending on mods. I say theoretically because I have never personally tested it, but have read that a few MB guys did.

For SOP, the SB will be more noticeable then the ECU tune. For example, we picked up 30RWHP when we did our tune and injectors and the only way I knew this was from the Dyno. It's the way these cars accelerate.
With the SB it was instant.

If you buy it through us or not I still highly recommend it and if you have any technical questions about it don't hesitate to call.
