I'll give that a try and see what happens. The tuner said to get something else and he'd have another go at tuning it. I didn't get cam specs etc.. for the motor when it was built because I was told that it was on a need to know basis....
The tuner did say that it was one of the crankiest motors he's had in the shop. Only specification to the engine builder was a race motor what I could drive to hillclimbs rather than trailer it.
