Sounds like you and me both... I'm running optimax, recent remap and fitment of a Bailey DV30. Also when driving uphill, power seems to pulse, it's contantly pulling but seems on and off.

More recently though i had a worrying few minutes. The car felt like a 1.2 having driven around 13 miles. I've read about MAF (Air Flow Metres) going, not sure at the moment, i've only driven it lightly on a short journey since so not sure if it's fixed itself?

Going for a drive later and car's in for service on 16th Aug. I i find out any more i'll let you know. Visa versa?
