TBH I would have gotten Jim to work on the map further.
I used to use him but got pissed off with his attitude and grumpiness.
I 'might' be back, but if I'm not Allen will take my car down.
My car is OEM and there was another car which was going in OEM guise too.
There will be a few cars there with known BHP/Torque so these can be used as a bench mark.
Your figures are good but would expect with further work they could be better.
This mapo was producing 250BHP and 250ft-lbs on Allens Toledo and Baz's
MK3 Ibiza both with similar mods as you and KO3s turbos.
You've got to remember, Jim is a business man, the less work he does for the money the better. See what Wallace rollers say and have a think about further mapping
