I have the Innovate XD-16 on two sleds. The guage installed on my M8 running twin SLP pipes works great when sled is running over 4500rpm have sensor in top of can. The O2 sensor in the M8 turbo does not work so well. Mainly a power issue because of power draw from BD box, oil pump, lights so on seems like not enough power left to run sensor. Iam going to try to install a seperate power source being 2 6volt sealed gels with a switch and only turn it on when tuning. Other guages include Boost, fuel psi, O2, BD box and stock tack speedo
