Just installed Software and I Can't Read File 2009 Chevy Silverado E35 - 12628594.hpt . Where can I get a replacement file ?
Where are the Repository files for Gen3 , I have a 2001 GMC Sierra 2500HD 6.0l Gas.
Is the EGR valve on all the time and at 100% ?
A long time ago I could climb a mountain grade with lots of power, Just like I was a Turbo Diesel, But now It's like I have a 3 cylinder air cooled engine for power. Unplugged the EGR valve and got back that power again. shouldn't the EGR valve turn off at WOT for performance ?
Thanks for any help......
