My son got this mapped yesterday. It’s all done by him with the exception of the exhaust and screamer pipes that were fabricated by his brother.
standard bottom end with a thicker head gasket and different valves and springs. Issue free dyno session making the power he wanted at under 9 psi leaving plenty opportunity for more boost with stronger internals. Positive boost from 2k until 8.2k


Off to the dyno

The important bit.

304 wheel hp😁

Engine bay will be tidied when the engine I’d out for forged parts in the future. Note the distributor with no HT leads as now on cop.

Nice touch screen monitor that displays everything the the ecu sees.
