It was only making 225rwkw stock (auto) but the motor had only 3,500k on it. Flash only and she came up to 262rwkw. Retuned at 7,500k with cooler upgrade etc and now makes 315rwkw. This was all on the same dyno - same tuner. Link to comment Share on other sites More sharing options...

I'm due for another tune very very soon- Very similar mods to you actually minus the venom cat (for now) + Stainless 4" airbox. So I'd be quite happy those numbers..... for now.Does your boost ramp on hard or progressive? Thinking about 2 tunes, one coming on hard say up to 15 then taper to 13 (just for fun times) and one just 13psi as it sits now. I'm making 272 rwkw without the F6 injectors in yet and a new tune to suit air box. :mail: Link to comment Share on other sites More sharing options...

The problem we all have is the standard actuator falls off towards max rpm. You won't be able to hold 15psi for very long mate. To remove it, you need to take the turbo off. Do that, and you may as well do the turbo mod at the same time. Then you ask yourself, do I want to bother spending money on the small turbo?I like the little turbo and the low down grunt it gives. Time over, even though I'd potentialIy only gain maybe another 10-15rwkw, I'd remove the turbo, mod it, ceramic coat the housing and manifold and upgrade the actuator. That would enable my tuner to hold say 14psi with no lumps in the mid range or fall off at the end. Link to comment Share on other sites More sharing options...

Mine is more of a hwy car anyway so I like the low down boost too. In the mid to top range you are already going too fast on the street.
