When it comes to personalized service from your engine builder/tuner, I am not sure anyone goes the extra step like Tommy from Chief High Performance. Call him on a Sunday when he is at his kids soccer game and he can talk you through a problem. Call him on a late evening and he will flip open his laptop, remote dial in, and check or modify a map in the tune.
In the latest case, call him right before boat school when you are about to go on a 44 Outerlimits with Chief 1350’s turning Arneson drives, and he is at the boat ramp, ready to jump on the boat and plug in while you run the boat steady at different RPM’s to make sure the you are completely happy with the boat’s performance and full potential!
