fitted k&n what next

[markd3925]

i have now fitted the shorter intake pipe, k&n panel filter and took the trumpet out of the air box on my 2.2 direct signum and can notice the differance.
what can i do next to improve performance without spending a fortune, the standard 152bhp i think it is doesnt seem alot for a 2.2

has anyone had the 2.2 direct remaped or had it tuned?

You're looking at 'proper' tuning if you want much more out of the 2.2...

Larger manifold, throttle body etc from 2.4, new injectors, fast road cams and a custom exhaust will give you some gains.

Rushy, Lizard or Vid would be your best people to answer that one
