Hi Danny,

Don't forget that allthough you may not have had 2bar boost on the RR at 4.5K, fully loaded on the road in 5th gear, it was probably easily making 2bar boost at 4.5K and hence running 14 degrees ign.

One of the problems with a RR, is just because you dont have det on the rollers, doesnt mean the car wont det on the road. Its very common to have considerably less load on the RR meaning that the top ignition line may appear to be fine, when in reality out on the road it is'nt.

However just so you don't think I am picking on you, I personally do not think anyone can blame you map given all the other possibilities. Yes 14 degrees at 4.5K and 2bar boost is optimistic, but no one can say it is wrong without testing the exact engine setup with your map out on the road. If it doesnt det, the ignition map is good!
