See above question.

I already have the PPP backbox and the intercooler hose section and will have the centre decat this week, is it worth me getting hold of the ECU?

What benefits will I see, smoothness, power (how much), torque, etc?

It seems that for the >£500 price tag for the ECU alone it is a lot of cash for little gain, could be just me though.

Any opinions greatly received, I am yet to try a PPP'd car so have no justified opinions myself, but how much of the power increase comes from the ecu and how much is from the exhaust mods.

Cheers
