top speed?
 

what is the offical top speed of a red top sr20det? i have a red top sr in my 91 240sx. i tried to push my car to its top speed. since i am using USDM's gauge, the top speed shown is 110mph only. i can pass 110 and all the way down to the bottom, until the needle can't go more further. and my the fuel was cut. is there a speed limit in the JDM ecu? how can i remove the limit and can i put a external gauge to show the speed when i pass 110mph?

Please search.
