First off, are you saying you had this problem before you purchased the chip off ebay?
If you bought it second hand, I take it you matched the chip up with your EEC Code right?
Next question: Did you program your EEC with the Hypertech?
I think I am right on this, you can't program your Superchip with the Hypertech. The Hypertech is used to program the EEC first hand. If you haven't done so already, pull the chip, reset the EEC (unhooking the battery for 20 minutes or touching postive and negative cables (notice I said cables only) together. Then check the Top Speed (be careful when you do) You can always re-program. Like I said, I don't know your mods so your chip might be doing something, like gear cal, timing, so on... Also, you didn't elaborate if you programmed your EEC with the Hypertech while the chip was in or if you even tried to program your EEC with the Hypertech.
