Looks like my HP Tuners is good till 8000 rpm. If this the limit of the factory PCM?

I dont know if it could ever be set any higher than 8000 using a GM tech tuner....
but no matter where I try...IF I enter more than 8000 and push teh save button...it just goes back to 8000

so I would have to say that 8000 is the limit.....

do you really want to try to spin the LS1 to 8000????

I don't want to steal this thread, but what IS considered red line for an LS1

depending on Cam and other Mods...
Stock 6000-6200
"Small" cams 6000-6500
"Big" cams 6000-7200

really I dont think I would take the stock bottom end much past 6800....but people are doing it....
