Dave @Torque Tronix is a good guy
300-305 is easily achievable with a good stg1 map, even on DynoDynamics.
But hes quoting 310 plus??
When I ran a RR day at SRR, which are considered the most consistent, I think the highest stage 1 was 295bhp.
Sorry but this sounds a little too much - Id love to see the before and after RR - Was it on AMD rollers..........
To be fair though its not about the headline figures, its how it drives.
