Speed limiter @110 WTF???

ABINOK · 03-20-2008, 02:02 PM

On an open streach of road, with no cars in sight for 3 mles in either direction, I opened up my GP today to find.....
a speed limiter at 110?

what do I need to rectify this horrible mistake on behalf of GM?
Can this be done without voiding the factory warranty?

ah hah. get a dhp or zzp pcm.

The MAN doesn't want you going any faster.

Zef_66 · 03-20-2008, 02:42 PM

The speed limited is in the PCM. Either buy an aftermarket PCM or have someone with a tuner change the limit in the PCM.

ABINOK · 03-20-2008, 02:45 PM

Im assuming that by buying a aftermarket pcm, then reinstalling the factory if I need service I could get around the warranty issues?

ABINOK · 03-20-2008, 02:53 PM

oh yea and DAMN THE MAN!!!

This is a Naturally asperated 2006... not a GT...
ZZP still work?

Before you get too crazy, make sure that your tires are rated for the speed. A blowout at 120 would probably be teh sux.

ABINOK · 03-20-2008, 03:15 PM

tires are V rated... and spanking new (worked that into the price of the car when I bought it)

I'm pretty sure ZZP tunes the Series III motors. There's a 2004+ drop down option on their PCM page.

(which confuses our Impala/ Monte owners all the time since they used the Series II from 00-05)

May I suggest an Overkill PCM. He can fix you up. If I were to buy another mail order PCM it would be from Will. He is the only one that builds a totally custom PCM based on your mod list.
