Im running 315/35/17's in the back and 275/40/17's in the front. I think this is what causing the problem to be even worse, but most cars are off by few miles. I tried hooking up OBDII on alot of cars and i noticed that most of them are off by 2mph at 40mph and the number go up to sometimes 7mph at speeds over 100mph giving stock wheels and tires.

I'm sure that someone would disagree but Honda's are dead on. The 929 and the S2 at top speed were exactly what they should have been on the speedos.

Any reason why resurrected a thread that is nearly 18 months old?
This is why: I finally topped out my S2 about a half an hour ago on the 135. It hit 148, I think it would have hit 150 if I waited long all damn day. When I reached 148 (I think that I was @ about 7800rpm) I then hit my 50 shot of ZEX and the car hit 158 (I think that I was @ about 8500rpm). I'm pretty sure the car would have hit about 162 if I kept going but I was afraid that I would melt my plugs.

I know what u mean... The drag timer takes ur avg. speed from the last 100ft only, but still that wont allow me to trap 112mph while my speedo is at 105mph. My speed should be 105mph while my speedo going 112mph, when that happen i can say thats normal, but when im trapping 112mph and only seeing 105mph at my speedo thats called speedo error.
Trap speed is your actual speed right? It is mathematically correct isn't it?

No, Trapspeed is ur avg. speed in the last 100ft if i recall correctly. Ur acutal speed will be 3-4mph higher.
