Wow, what a difference in the mid-range of the power band. My car had an obnoxious hesitation right around 3000 RPMs that made it annoying in any normal driving. I replaced the plugs, air filter, fuel filter, distributor cap, wires, and it still persisted.
Well I put the SW chip in Friday and it was immediately gone. The car is so much more enjoyable to drive on the streets as the powerband is far less peaky and far more usable from 2500 - 4000 RPMs.
Overall, the swap took about 30 minutes, the hardest part being bolting the Motronic back down underneath the seat due to the awkward access.
