The dyno run was done in 4th gear (205kph @ rev limit), so the gear ratio is not 1:1. The actual torque worked out to 440Nm (330lbft). I am having another dyno run next week-end (hopefully in 5th) to see what has happened over the last 2 years. Then I am cutting out the cats, maybe putting in a high flow set of resonators where the middle box is and fitting a K&N panel. I will be making one change and then dyno, to see what increases I get. I'd love to get some Dinan bits, but I would be concerned about any gains, given that you guys run such low octane fuel and I'm running on 98 Pump gas.
