yep, just take it out.....
I have one I'm not gonna use its for 06-07 if anyone wants to make an offer

finally got the thing installed today.. this is the best pcm ever.. it's so cool to set your own rev limiter.. i got on it a little bit today.. seems to pull pretty good.. can't wait for the roads to be dry so i can take it on the highway. i'm seeing crazy ass gas mpg though.... is that normal? not that i'm complaining or anything lol.

i got a 2.8 inch pulley.. 42lb injectors, intake, 3 inch exhaust. yea i know.. people are gonna say i'm maxing out my injectors. my car's been running fine on them, so no need for me to change them yet.. although people have been running 60's with this pcm.. but i'm worried about plugs lol..

it didn't control the 60's at all man.. AFR was waaaaay rich... but don't set your rev limiter over 7400 rpm MAx... or kiss your valvetrain goodbye

I didn't log it so I can't be certain what the readings were. It ran, better than the stock setting with 60's did.
Setting the limiter that high makes perfect sense. Just remember not to abuse it by taking the car to the limiter when its at 7250.

i don't run my car that high in the rpms very often.. unless i'm at the track. anyone else seeing more boost with this pcm?? i don't think it bleeds boost off in higher rpms.. cause on one highway run i saw 20psi.. not sure why.. may have been the weather.. but i thought it was weird.

So the Stage 3 PCM can't handle the 60's? I would love to have HOM and the rev limit adjustment. But if it cant handle the 60's which i already have installed in my car with the Intense stage 5 tune i might as well stick with that
