Standard Boost

[PukkaSilvia]

I used those orange hotwire leads on my 8v engine and they deteriorated and were nackered in under 2 months. So i bought some Magnacore leads and i did notice the difference in engine performance.

As Shaun says and set the plug gaps to .9

Thats a very healthy bhp figure you have there considering. Exhaust and air filter modifications will help just as much as a boost increase
