Yes, i'm sure the tuners will tell you all of there secrets for free

the fact is that if you want 300bhp,then you'd ideally need to lose the KE-Jet,you can still keep your inlet manifold etc,but the metering unit has to go.

Cossie L8 management would be my choice,with a set of greens or greys and a T34....of course you will also need a steel bottom end ideally to cope!

so either accept the limitations and enjoy your standard looking engine bay,or get new management with a 'tiny' difference
