12200411 PCM swap for 1996 to 2000 GMT400 trucks

[Lextech]

It is an upgrade over the 96+97 but, It is not what the 0411 is.

I didn't get a PM. I need your E-Mail address and year of your truck.

411 pcm swap and CA smog

Hey guys... Im reposting here and there im hopes I can get an answer here, & hopefully help sum1 else out...

Has any1 had any issue passing smog tests in CA after the 411 swap..? I heard that it will not pass because the pcm will read as a 02 chevy express van... And I think just on looks... That in CA u can not swap pcms... I mean sure I could just swap my old black box in but c'mon re-pinning once is hard enough im not trying to do this every time im going to smog... so looking 2 hear back from u guys especially u Californians...
