Okay switching the Rally stock tires to HPI Tarmac tires yields a 4 mph increase at top end. Maybe more, car was last run and tuned in 35-40* weather today was 50 and windy. Car was running rich though and I didn't bring any tools. Prior top speed on the Rally was 36 mph with Jetpro and 990 car, running 31-29-26-24. Next run will be 35-25-26-24.
