I have a 2010 WRX, OEM Cobb stage 1 tune. 7K miles. Drives great. However, I am having an issue:
Sometimes when accelerating from a roll in 1st or second gear at WOT, there is a hesitation/loss of power at high RPM. This only happens on rolls with the clutch fully engaged; never during standing launches. What could this be? A tuning issue? Boost leak? Traction control? (didnt notice any lights). Thanks.
