Don't go too low w/ deletes or you might pick up vibs in the exhaust. If I could bump mine up 10-15 rpm it would be perfect as far as vibe free. It currently idles right @ 700. By far my one & only complaint w/ the deletes, it's a whole new truck in the power & fuel econo dept!:thumbsup:
No idle adjustment.........the feds have it locked out.That would change emisions so it is written into the software.There is a high idle that can be enabled using the starscan,but if you touch the brake pedal it gets canceled/reverts to normal idle speed.
i had my dealer, great guy, hook up the starscan to have a look at the rail pressure to see if it matched my ISSPRO, while he was there i asked if it could change the top speed, he said there was no way to do it on the 6.7's. if you want top speed changed, your going to have to pick up an XRT/smarty etc.
