I'm planning on doing some logging this Saturday morning (if I can drag my lazy arse out of bed!) to try and diagnose a possible boost leak/failing MAF. When I get my toe down I can hear the turbo and it sounds like normal but the car seems to have lost the kick it had before. I plan to log the following blocks and wondered if anyone had any others to add to the list: - Block 1 - Block 2 = MAF - Block 20 - Block 31 - Block 115 = Boost - Block 118 = N75 Cycle All of the above should give me an idea of boost, MAF, Fueling, rough power figure etc. If anyone has any other suggestions please post here.
