Yes, it is 30bhp gain....of course I will double check with him though.I will also find out a torque figure for you.
Yes, he has chipped D's before. Ray carries out development work for many tuning companies, I belive (don't quote me on this though) that he helped to develop the OneClick. He also works alongside marques such as Mercedes Benz, Ferrari and Noble to name just a few. Ray's real talent seems to lie in ECU re-mapping so I would be more than confident getting any ECU work done by him.
I believe this price also includes before and after rolling road sessions.
I'll confirm a few things with him shortly.
Cheers mate, LB.
