Really chuffed with it, but i don't think its standard.

I'd appreciate it if someone could enlighten me with their YB wisdom on what to look for.

The car drives fine, although when at high boost in 5th the car let off on its own as if it had a fuel cut and dropped a fair amount of smoke out the rear end. That was 200 miles ago and hasn't done it since.

Going to get it in at Norris at some point if and when they can fit me in to get it all checked over as i'm worried about abusing it now.

No knocking from the engine, no piston slap either. The lifters sound abit tappity but other than that she's quiet. No smoke on startup or idle
