Just got back from having it mapped ran like a bag of turd for the first few miles then I noticed the engine sounding a lot sweeter and the throttle was more responsive and no smoke. The power delivery is so much better aswell pulls all the way to 45000rpm. He said whoever mapped it before just had it over fuelling I didn't realise how bad it was running until now much better

Airtec is good for the money and will handle bigger turbos power fine.
