Hi Mankee, Over the first 450 miles the engine got better and better each time I took it out. It seems to have plateaued now. (I swapped the running in oil out at 600) It's also now running very rich, which according to Andy is because the compression has come up due to the rings bedding in. More compression requires less fuel. We were going to adjust the map on sunday as its still limited to 6500 rpm, however the 02 wideband sensor is faulty so we've rescheduled for this weekend. (Pending a new one arriving in time). It's a lot of fun. 2 things that now need doing as a result though. I run 15" wheels, and just discovered that the tyres are nearly 8 years old. Eeek. No wonder its sliding all over the palce, even worse since the upgrade. (They're CR500's) I'm trying to find 13's and I'll get the new ZZR's. 2nd thing is the brakes. I actually thought they were pretty good until I drove Andy's integra (standard 280mm single pots with DS3000's). I want my eyes to pop out my head when I pres them. :)
