After spending hours on the net and not finding much info I thought Id post my Dyno chart. With a DPF still fitted 190bhp seems to be as safe as you can go. Removing the DPF will increase it to about 205-220 depending on who does it. I actually stumbled across a remaping company Home - Performance Torque Tuning Specialists that were 5 mins from my house so I did a lot of research to double check they knew what they were doing and was happy to let them loose on my car. Especially as they are mapping Touring cars that are to be appearing on SKY tv. Performance Torque - Tuning Specialists - Wall | Facebook I want to give it a few days of hard driving before I can confirm the results but from the little run I did today all is good. Its a very smooth power delivery so I'm happy that the clutch will last and I am astonished at how the engine loves to be reved. I can't remember if it was 4th or 5th gear I was in but flooring it from 2k RPM it just kept pulling and pulling up to 4.5k RPM. Once I get rid of my heavy right foot itch, Ill see what effcts it has on the MPG. With my 15-20 min spirited drive down a country lane my MPG didnt drop below 41.4mpg but we'll see how it goes tomorrow.
