Sold and fitted loads, including on my own cars and rate them highly ![happy2 :happy2:](https://www.mk5golfgti.co.uk/forum/Smileys/newsmileys/happy2.gif)
Well if you rate them Dave, that says a lot.
Plus i find it hard to believe that Forge would manufacture a product which was complete gash as their Twintake is clearly good and I have the quickshifter which is decent.
So if i fit one Dave, and increase timing to say, 6 from 5, will that increase performance especially in the summer months?
