After initially thinking that I could live with the drive of the 2.5i, I decided that if I was going to keep the car longer term I needed to address the "slug-like" performance.
So I did some timed runs and a dyno as a baseline. Stock the car runs 0-100km/hr (0-62mph) in 10.0 seconds flat.
I've also been working with Matt (KiDo Racing) for a tune for the Gen6. He's managed to crack the Hitachi ECU and the other day when he was in town he reflashed it with an updated ECU/transmission tune.
Here's the before/after dyno comparison - red (stock), green (tune)
Power is up overall, however torque is a major improvement across the whole band.
AFR's are sitting around 12 which is nice and safe but means there's a bit more there...
And finally on the road the 0-100 time has dropped over a full second an it now runs 8.9's consistently.
