Fair play Ruan. But if the throttle is looking like the most likely culprit, how has Ben found himself with these problems? He has used the jp4 throttle...

Thinking about the pulse tuning side of things too, would the pulse difference of the '6 inlet manifold really affect the running of the engine to the degree previously mentioned? IMO the same suggested problems would be reached by fitting the '6 exhaust manifold, or an aftermarket exhaust with back pressure less or more so than stock... Just giving an incorrect exhaust pulse rather than inlet pulse...

This is of course suggesting that the pulse is the underlying problem here, and I fail to see how a mismatched engine pulse can cause a car to run 98bhp on the rollers....


And yes I have had a few beers. This ^^^ makes sense to me, but i apologize if it is just drivel...
