(Third time I've tried to reply.. not sure if something I'm doing or just not waiting long enough for it to post...)

Thanks fellas. I was always going to take it to someone who knows what they're doing to give it a decent tune. Don't see the point in paying someone to swap out a pump.

I've had a bit of a look at your post MR and looks like there's a lot of info in there. I'll be referencing that for sure once I start pulling bits off and trying to fit my intercooler. Looks like I've got the same one as you only half the size.. I've also only gone 2.5in on the IC side of the plumbing as I was a bit worried about getting it through and around where I wanted it. Hopefully won't restrict things too much.

The parts are slowly starting to arrive!
