I pulled the code:
DTC P0234: Turbocharger Wastegate System Malfunction

I recently installed a walbro 255 and 264/264's.

Any ideas for S-afc settings or alterations to buschurs stage 2?
Possibly some colder plugs for starters?

MODs are:

MAF induction pipe INJEN kit w/ upper I.C. piping & Forge D.V.
Boost set to ~20 w/Halman pro rx
Full 3" Turboback

 

when you connected you Boost Controller did you disconnect & remove the stock Boost control solenoid?

if its not left in the car with the connector plugged in it will throw a code.

 

The stock boost controller is still plugged in, but capped off, and I had a P.E. boost controller before with no problems. It statically charged and shorted on me however.

A fuel cut come from too lean or rich? My Karman was close to 1700.
