AC makes no difference as the compressor shuts off at 50%+ throttle.

If you're not starting the races in the right gear, then the extra lag this piggyback creates initially is killing you. YOU MUST start in the right gear. That's #1. #2 is that you must be side by side and start the race at the same time. All things considered, this tune isn't going to let you run away from him over such short races, especially ones where you're starting at too low an rpm and in the wrong gear. You're basically arranging the races to his car's benefit.

There's no getting around the laggy spool of a piggyback. It's the nature of the beast. Do a search and you'll see that all piggybacks do it and it's worse when punching it from a low rpm and tall gear. Additionally, it's worse if the piggyback is commanding a lot more boost than stock. The DME flakes out momentarily as it tries to compute the conflicting data. That's why there's more lag and in some cases, inconsistent power delivery. If you want more consistent power and less lag, then turn the power settings down a bit.
