help i cant remove speed limiter

so i was trying to remove the speed limiter from a 2001 yukon 8.1L today..

so i open my flashscan i go to SPEEDOMETER and set my ETC Govern Speed Threshold to 256MPH then go for a drive and BAM dam speed limiter still there??

is there anything else i need to do

thanks guys

help me out here guys ...

what i did was....
under speedometer i put 256 in the ETC Govern Speed Threshold stock tune when i hit 98MPH it felt like truck was out of breath with out feeling anything ...

but now after the above tune there is this really hard (fall on your face cutoff thud) feeling when i hit the limiter as if someone hit my truck from the back

so it must be something else in a different cal screen what am i missing here just cant figure it out..

Check the following:

{B3303}
{B5401}
{H0108}

nop that didnt work i moved all the rev limiters to 8000 RPM and speed limiter to 200MPH

speed limiter used to kickin at 98MPH very smooth you dont feel anything....but after the above changes speed limiter kicked in at 106MPH with a strong almost feels like you hit something...

did i miss anything else

thanks.

Send your .tun file to me at SilveradoSS (at) insightbb.com and I'll take a peek.

just sent it to ya....

thanks bro

Some of our earlier .cal files did have one of the ETC speed limiters missing.

I know Rick has the updated files so he should be able to do what is needed.
