Well said D.

I set my RPM limit at 5500 just to be safe.

 

wow u got me there but really the only thing i want to get out of the programmer is just the ability to rev up the engine i really dont mind the top speed limiter

i just cant stand not being able to rev up the engine...

 

the only reason i would buy one of those is to remove the top speed limiter. i hate not seeing triple digit numbers. i know how far i would be able to push my truck too if i had no speed limiter. i know for a fact my kuhmos can handle going 110. my dads acura could easily reach 150+ but i know for a fact that his tires and brakes and suspension and everything else on his car cannot handle it. i know this b/c i got it up to about 140 and the car was very unstable and took a looonnggg time to stop it. i did this on a really long road where there were no other cars and i would not reccomend anyone else trying that myself included. ill never do that again lol. after driving that fast you will speed and not even know it. i was going 100 and it felt like 50 after that. all im saying is to realize what your car/truck can/cannot handle before you do anything with it. my ball joints are bad and i think its from off roading and taking exit ramps at double what the speed limit sign says
