Thats why there is a group [ in USA Volvospeed forums ] that work with the standard ECU and modify as much as they want , ie big injectors,turbos,TCVs , exhausts,etc . They dont need to EX$$PEND on ECU so save a LOT! Worth a look or try.

I'm gonna get the piping together over the next month or so (I've got new wheels and those sexy angel-eyes to buy first) and surgery shall be performed....

So does a BOV no longer go in the top pipe with a RIP? Assume the function alters as the flow has been reversed?

I am presuming the dump valve principle is still the same.That being it should be position in the turbo pipe work as close to the throttle body as possible.So with the rip pipework this would be in the pipe from the bottom of the intercooler to the throttle body.Confirmation appreciated

This seems to concur with Duane's thoughts on the matter. So assume this is correct.
