Sunfire 2001 2.4 speed limiter

How could we remove the speed limiter with VCM suite ?

I first did it on my cavalier ecotec 2005 by putting higher values for the speed limiter (1 and 2 ) and it worked without any problem. But when I went to do it on a Sunfire 2001 2.4 it have not worked, I edited the same values at the same places but the car is still locked at 105mph :(

So I read the car computer and good values was there.. HP tuners web site is telling that this car is suported by the software ( I used VCM suite 2.1.14) but it's not making any change...

I also tried a complete write of ram, slow speed, high speed..but problem looks like it something else or this type of motor is not suported maybe ?

If anyone have an idea of what could be wrong it would be very appreciated!
Thanks in advance!
