The gain was after the tune. I did a total of 7 pulls, all in 5th gear. The pulls before the tune maxed out at 188.6hp at 5220rpm after that it dropped to 150hp at higher rpm.
The Eurocharged pulls similar until 5220rpm. As the rpm climbed the hp kept going up. At 5857rpm it reached 199hp (131mph). it didn.t start dropping until 6437rpm and 141mph.
I'm looking at the charts and graphs from the dyno. The Dyno was was done at JBA Racing on a Dyno Dynamics Dynamometer.
