    I donít know if it is in fact a result of a quicker throttle by wire signal as they advertise or the module tricks the car to increase the throttle under lighter pedal engagement. Either way, very worth a few hundred dollars in my opinion!

    It's the latter - they just increase the throttle body opening per pedal input. I wholly agree that the difference is wonderful, though! Makes rev matching a fun game whereas I found it to be a chore on the stock tune.

    Interesting. Will this cause excessive wear on my fancy new TB?

    I used Bimmerbrakes gen 3 headers. Theyíve been holding up well. The guy that does my fabrication said they are very well made. He makes custom headers from stainless and titanium so I respect his opinion.

    Sprint booster is great option on a stock car but after I got headers, the car was so responsive, I didnít need it anymore. Ended up selling it.

    I tried the SB for a bit and also found it to be too much with a shark tune (that increased throttle response) and 3.38 diff. The car was just too jumpy.

    I really liked the SB with the Dinan stage 3 tune and stock manifolds but it's such a better car with headers.

    Makes sense. I'd bet that the throttle adjustments on the Dinan tune aren't as aggressive as the Shark. Turner lost access to the Conforti tune files and their canned Shark tune's fuel trims are crap now, so they likely go overboard on the throttle response to make it feel anywhere close to the hp boost they claim.
