How much do they really improve an Apex, Nytro, RX-1, whatever. Nowdays we got better boards that allow snow to fall through, what else does the tunnels improve? Reason I'm asking is that I've done pretty much everything except aftermarket tunnels, haven't even been on a sled with an aftermarket tunnel, so it's hard to justify the price tag on one without really knowing how much of an improvement to expect.
