Mine is off by about 150RPM at idle and it gets worse the higher you rev... this could be modified so you could calibrate it, but it's not worth it in the least. Also, if you're running a R154 the numbers will be off too... their gearing is a bit different for each gear.

i get what your saying but it says my car at fuel cut will do just at 86 i was like 500 rpm off fuel cut at 87 and my tires are almost 1 inch shorter than stock that means im revving higher to go the same speed so it just doesnt make any sense to me... but its not that important
