you sure can clamp it in. it is so easy to install. :thumbsup i wouldnt recommend it for a permanent install though. mine is temp.
cruisin at 45 i am around 1200 i think. cant remember. about 900 or so at full warmth idle. lower than most i believe. i have a strange wiring issue though, when i turn the running lights, the egt gauge resets itself. dont know why. they are all plugged in the same way but that is the only gauge that does it. oh well. i will be looking at re running the wires shortly, i believe it is having an effect on the performance. other than that, i am running a solid 11psi. spiked it to 11.5 for split second once. oil pressure gauge works awesome no probs at all.
