Edgar, there might be a few tips on running a stage 1 PT atx a little better.
1. Let auto-stick shift for itself (it will automatically, shift around 6200 RPMS)
2. Better tires, set psi around 25 for the front tires.
3. Launching at 1900 - 2100 RPMS.
I'm sure you probably may or may not know these, but I'm just tossing these points up just for simple reminders.
Cirrus might be lighter than the PT, therefore they go faster
