Higher you rev, the bigger the RPM error. About 200 at idle, Don't know why they bothered to include them. Actual 6500 buries the needle on the 7000 RPM peg. I get calls all the time "Your shifting my car too high!" Or, "you set my rev limiters too high!" Like pulling teeth to get some people to check them with a scanner.

Take the clear plastic lens off of the cluster and very gently lift the tach needle up to remove it. Simply replace but factor in the right amount of correction. Just lightly press it on and it will he accurate however it might take a couple of trys
. Mine is accurate at all rpms.

Regardless of whether or not it's an auto really doesn't matter. If you're worried about shifting the trans does not rely on the signal from the tach. I guess if it bugs you that much then you can relocate it? Personally I wouldn't go through the trouble.

4.11's but reads as if it has 4.56's. mph is spot on. Rpm is off. I verified everything via scan.. Car is tuned correct for tire height and gears. It's only a eye sore to me.. Was just wondering if there was a fix. After this thread in really not worried about it. Ed had me at ease with his first post
