Letting up and then more throttle could have unpluged it. Without reading the code it is guess work.
We did put the small pulley on once and the H2 launched good on first take off and it was awsome at 10lbs. of boost. If You ever saw KENP's launch video in his LPE SC setup it was like that and magnified. I after watching Ken's launch was able to anticipate what was coming but, it was just even more torque steer at 10lbs. of boost than i expected. I after that got check engine light and rig ran OK but, nothing like when the kit pulley was on with kit tune at 6lbs. of boost. This was all predictable we were just messing around. We have on the WOT runs failed to get out of the rich reading though.
I would still go back to install shop and have it all checked. Better safe than sorry.

I hate to thread jack, since this seems very important, but, i have to ask, what did ya'll do for the tune at 10lbs? What was the AFR @ WOT at 10lbs before she went to limp mode? Are yall running a 112 blower with a 67-70mm or STOCK TB?
Sorry, conrad, had to ask?!
