The ASOG guys have a mod they do for the TPS that you should check out.http://www.asog.net/wrhinehart/tps.htmI'd be interested to hear of someone doing this on a 2GNT. Should be exactly the same procedure. Personally, I'm not much into drilling away at pricey electronic bits like TPS sensors, but the ASOG guys all seem to love the mod. juan
