i beg to differ. but then again mine makes insane power numbers. but my car pulls all the way to 135 with no problem.. after that it take all of florida to reach 150's
its an easy mod. there are two ways to do it. above the ECU is a white plug that leads to your gauge cluster. theres a yellow wire with a green stripe. cut it. your speedo will still work and your ecu wont get a signal. after you do this yuou have to disconnect the 4th and 5th gear sensors on your tranny.
the othe rway i did was disconnecte fthe sensors and ran a toggle switch inline with my vehicle speed sensor. when i hit the swtich. it opens the signal and my speedo goes to 0. and the cars pulls.
