2007 4.7 here,again top speed limiter?

dont forget the top speed limiter setting do not work on the 07's,i suspect on other models also?

did you ever get it revised?

thanks,will be waiting.

last tune,should be a little fuel enrichment and limiter set at 140,tried 155,190 also.

put the 87 tune on,modified the fuel and top speed limiter,the fuel worked but the truck still shuts down at the factory setting,also the 91 gas tune seamed to disapear from the programer when modifying the 87 tune?does the speed limiter setting work for the 87 tune?
