Thanks for the reply Mike.

The car was live mapped by msd.

The intercooler is an rs500 item and like I said it just doesnt seem to have the punch it used to have even on these cold days on the road. Hence why I took it on the rollers to start with.

So thinking more like maybe a sensor down or lack of compression or something?

It doesnt miss fire, its using no more fuel, no oil leaks, idles finem drives normal, boost ok etc Maybe its just me use to the power.
