That number is at best a guess, you may have cause a restriction or an excessive pressure problem. I would never start shimming your return unless you have a gauge to go by. You may have already had your 65psi and now you are at 85psi or more. It's just a guess at best. Remove the edge, remove the bb, check the nut on the IPR as it sometimes get stripped by someone that don't know it is very cheap and strips easy, check all your connections and oil level. Give it a go and see how it does. You can start adding stuff back until problem returns and then you will know.

Alright I did a search and I came up with a bunch of stuff so basically I'm good. I already put my chip in and went out for a spin. I was out for 20 min. or so to get it all up to temp. then I flicked it up from 50 to 100 and gave 'er hell. I was so busy hanging on (holy crap) to notice when it came on but when I got home the check engine light was on. Checked the codes AGAIN and came up with the same P0603 AND P1211 (ICP not controllable - pressure above/below desired). What the heck - is thing gonna set off my check engine light and throw codes every time I get on the go pedal?? The check engine light stayed off right after the install so I know it's not the connections... Anyone have this crap??
Chad, are you pulling our leg? While I don't post in the SD forum alot, I haven't seen you in while. Is this a test to see who remembers you? If I'm not mistaken you drive one bad *** rig that's modded to the hilt. "Superchips, P1211????" Newby questions...... What gives?
