PS Just did the stage 2 filter and kev mod and O2 last night. Tonight is the test so quite nervous at this point.

From what I have read on this (only had my XT 3 weeks and going through same process) if you have the Stage 2 air filter, then removing the snorkel only gives a further extremely small increase in air flow hardly making it worth while. I think, somewhere in "Kev's" links posted above you will find the air filter flow comparison tests and also the HP gains of each mod.

I haven't removed my snorkel and with the DNA stage 1 and 2 filters it made a massive difference over stock filters with everything else the same (ie cans/fuel mod/etc).

Enjoy your new (and improved) XT.

The snorkel is a significant restricion on the air flow, you are not getting the full benefit of the dna stage 2 conversion. Remove the snorkel!!

Pleiades, can I ask where you got your Dyno map done please? I'm assuming it's local to me - I have just got a PCV and 02 Optimizer.
Thanks

I've used Seastar at Newton Flotman in the past and they've always done a good job too.
