Half bridge port on stock ecu.

[RETed]

Here's the problem...

You increase the breathing of the engine, but it's still being choked by the (stock) intake manifolds and (probably) the exhaust.

Ask the BP gurus and flow is everything...
There's a reason why they run short intake (manifolds) and big exhaust systems.

This is why people ask: "why?"

Sure, it'll run...
Run efficiently?
I personally doubt it.

I personally think the ports are cut really bad.
"Well done" would not be the words I'd use to describe the port job.
