A scratch my head moment! - ZR-1 Net Registry Forums

Well I just changed my rear ujoints out for new series 1350 spicers and changed all the fluids with fresh getting everything ready for the Texas BBQ. So early this morning I take it out for another balls out top speed run which I havent done in 2 years. Since I'd done all the suspension stuff/new tires everything balanced Spec stage 3+ clutch blah blah blah! So did it and car runs freaken great and like always runs right up to 179mph and handles smooth as glass. But while I was at light spead I looked at where my tac was. Last time at the exact same speed I was at about 7000 to 7100 rpm's. This time it was reading 8000 rpm's.

No doubt my tac is off but what would cause it to go out of calibration that much? Also my gamin GPS said 181 mph. Ah! Whats the difference 179 or 181. At that speed who cares.
