I have a 2000 b16 with a 95 gsr head with a lot of bolt-on's .I have a chip made by John Vega it has a 2-step at 3000 rpms ,so i finally got the car runnin i was test driving and it won't rev past 3000 rpms whie driving. I checked all my sensors and cant figure it out , someone please give me some ideas as to what could be causing this problem.

 

Is your check engine light on ? If so, what code is the vehicle throwing ?
Is your speedometer working ?

Your speedometer must be working properly if your running a 2 step.
You also must have no codes in order for your vehicle to be operating properly.
Check to see if you have any vacuum leaks or if your tps and map sensor plugs are swapped.

 

 

you should also check your chip if chip is in wrong it could do that ( it happend to me )

 

Thanks guys for the ideas, the only check engine code os code 6 coolant temperature sensor which ill be fixing today. The speedometer i havent checked i didnt even pay attentiion to it i know that the tach works but ill for sure check on that ,but the map sensor and everything is in the proper place so ill just double check everything. Before i used my computer with the chip in, i put it in my boys gsr and it ran serious as shit so i doubt that the chip is in upside down but i will double check thanks again guys.
