100k mile service

[Sweep]

The ol' T5 is fast approaching 100k miles, I've just replaced the TCV for an IPD uprated item but us there anything else around this mileage that's wise to change? I'd like a bit more power this year so want her running tip top.

I was reading somewhere that the 850 T5 Lambda sensor (front) should be changed around 100k miles.

I just did the BCS/TCV on my own car, but with a standard item, quite a big difference and found some missing boost, how did you find it?

Agreed! Although it's now just amplified my initial problem :(

What's the problem Sweep?

It can be very hesitant on boost, it feels like it's starting to build boost but then hits a wall, then continues building until it hits another wall through the Rev range.. I've ordered a load of vacuum hose to replace the standard stuff but I'm not convinced that's the issue.
