You may want to talk to a good tuner if you want to find out how far you can push it without breaking your manufacturer's warranty if that's an issue. The problem is that no tuning product design shop has a business plan that justifies much time spent on developing 50-state legal products for a SULEV engine that only exists in about three states (I believe). You will have to get past the N26's self-imposed restrictions if you want to jury rig something like a Dinan S4 Big Turbo tune designed for the N20. Dinan will wink and tell you it's possible but I wonder if they would allow their vendors to do this to your N26.
