i swapped the stock pulley for a 3.4" several months ago and ever since my GTP feels like its "lurching", or "surging" in 4th gear. it only does it while slightly accelerating, and is really pronounced going uphill. it almost feels like a belt slipping
but wouldn't that happen in all gears? it stops as soon as i stomp on the pedal and the SC kicks in. has anyone encountered this before? its driving me nuts!!
