it being on 150 shouldnt be a problem. when i turn my car off, mine doesnt go back to zero all the time. but as soon as i crank it up, it swings back to zero, then works its way up as the temp. increases. only trick i can give ya is tap the runner on the exhaust manifold thats on the farthest drivers side. goodluck with it. www.TeamKLR.com 1997 Silver RS Wiseco 10.5 Pistons Eagle Rods T3/T4 Turbo Custom FMIC Greddy Exhaust 440's
