Yesterday, motor stalled Twice, one after a high speed run (1500 feet WOT on hardpack) and deceleration on idle, when touched the throttle, motor shut down. fired back right away no code, no overheating.
Other time yesteday too, we were drag racing, Wanted to floor it of Idle (1500 rpm) and motor stalled, fired back right away.
Can this may be cause by the lack of restriction of the straight pipe exhaust.
Temp was around -25 celcius.
