I'm about to install some Headers, Tunnel plate, and get a Tune on a 13' GS A6. I've noticed when reving the engine in Park or neutral it kicks out at 4k.

I was reading (True or False...) that with the M6 the Rev limiter is set much higher at 6500rpm.

So to my question:
Would raising the Rev limit to 6500 (and or Reving it to that in Park) cause and damage and is there any reason to NOT attempt this?

Revving the engine that high in neutral is a terrible idea. What could you possibly need to do that for.

For what purpose would you want to rev the motor that high for in neutral ??


It already should be shifting at pretty close to the red line if you have an A6

When you stomp on the pedal at what RPM does the motor shift into 2nd ? ... I bet its real close to the red line if not right on it

Because it's super cool guys, come on

you can mess with the tune and raise the park neutral rev limit, but at wot i think all the a6 vetts have the shift commanded at 6400 and limit at 6700 and park neutral at 4k

LOL - there you go.....

The 4000 rev limit is usually used when the eng in COLD or below operating temperatures--revving it up beyond 4k is just plain stupid !!!let the rice burners rev their engine up to 6k when cold- who cares if you blow up a $1500 car----
Now if you are serious about raising the rev limiter after warmed---The only advantage would be if you raise the SHIFT POINT RPM's There are 2 RPM limits
on an A6 ---the 1st limit is the "shift at RPM limit" and the 2nd is the "safety rev limiter"
The only time you should alter the shift point RPM's is IF you install a cam where your powerband goes higher than stock otherwise there is NO advantage to rev of a stock cammed engine beyond 6000 RPM's as above that it actually starts making LESS HP

Ideally you want the shift to happen at "peak HP" and after shifting you don't want the RPM's to drop below "peak TQ" so a stock cammed engine it set spot on as far as shift RPM's is concerned----

Stock cals usually have a 4000 rpm rev limit in neutral or park.

The very best way to crack Pistons is to rev your engine to extreme limits in neutral.
