does raising the punch% decrease mid and top end speed?

You can do the same thing with your finger on the throtle. Just dont pull it as fast and its the same as punch control, only you control it.

I seldom run more than 10% punch control - it works great off the line, but it any higher setting creates a very "muddy" feeling in the mid and upper rpm range, making timing more difficult(the delayed reaction doesn't curve away as rpms increase). I have had good success with the throttle curve, though. I use a mild curve, basically 50% throttle on the trigger yields about 40% on my curve, and 90% throttle on the trigger yields about 80%. The curve slopes mildly at low throttle input and steeply at the end(so if I really want it all, it is available with a hard squeeze). It takes a few tries to get the throttle curve to a nice, driveable and predictable setting, but it works far better than punch control IMO.

THe throttle curve is the best tuning device for the Mambas. I run a 1512 1.5d on 4s in my rc8. I have my punch set at ZERO. With a linear throttle the car is practically uncontrollable on a track. Way over powered and very hard to keep the back end in control. With right gearing I can easily get the car up in the 60s.

I adjusted the low end of the curve to where it is very soft then pretty steep after half throttle and it works perfectly. I can creep around the tight turns and short straights and if I need to clear huge triples or doubles with very little run up, all I do is grab full throttle and it is bye bye nitro.
