ISO standards specify that expected load range on turbocharged engines is from 0 to 400%
BTW absolute load specifies how much air is in the engine compared to its displacement. Naturally aspirated engines can't reach more than 90-95% load.

We are currently investigating load cap reasons in the ECU code. We hope to find a way to get rid of it in a nice way that will not cause any troubles with AFRs.
Steve is able to reproduce load capping even with stock turbo and ported head.

Steve told me he was looking for a male connector to fit the stock MAP connector. The plan is to make a plug and play adapter cable.

Looks nice!
How plug and play is it? Is connector the only difference?

Thanks, these are very good ideas. The software is currently able to read/clear DTCs on all modules that are on the CAN bus. Problem is that ABS/DTC module in the Mazdaspeed 6 uses a different bus for diagnostic communication, which seems to be a proprietary protocol. So there is a possibility that ...

What's the intended use for that dielectric grease?

Nice how-to Steve!
Too bad they don't sell a MAF cleaner here that adds 10 horsepower to the wheels..
