I was driving down the road today and the service engine light kicked on so I plugged up the predator and this is what I get.
P1151 Lack of H02s21 Switches-sensor indicates lean (see p2197)

then the other one says, P0234-turbo/supercharger overboost condition.

I have had the P0234 before and I cleared it and it never came back on until now (it kicked on once during the spring). I really dont know what is causing it. Any ideas?

Also I just added the JLP comp. R exhaust (which sounds insane) the other day and today is the first day I have had the truck out.
