I have a stage one on my 06 rxp with almost 80 hours, Yesterday I went out air temp was low 70's water high 70's - low 80's, water was glass, not one ripple and after a couple runs I only saw 7800-990 rpms every time........Then I do a couple more and the rpms are 8000 to 8250 but bounce back and forth constantly, so I took it easy and idled for a while let it cool off and tried it again same thing 8000-200 but still bouncing...just wondering if this is normal during a temp. change or if you guys no what is going on? Thanks mike
