My recent experience with the Turbo Control Valve on my S70R.
Have read a lot about these and always felt my beast lacked a little in the low revs area, so while on holiday in Florida had IPD deliver a valve and some pipe to the villa, expensive way to save on p+p!.
Fitted the IPD valve on my return along with replacement piping and there was a better low down responce, but this was at the expense of the mpg dropping from around 24-25mpg to 22mpg, ouch!
Ran it for a few months but could not improve the mpg, I do the same daily runs.
So fitted a new Volvo valve, within a week mpg back up to 24.6 and to be honest cannot say there is a big difference in the way the car drives, better than the old valve and pipes, but very little difference to the IPD varient.
