I have kkk k16 with FVD ECU, but i cant seem to get above .9 bar of boost. this setup should make 1.0 to 1.1 bar. I have changed my diverter valves, but that didnt help. does anyone have any suggestions ???

 

First check for codes with PST2, PIWIS or Durametric. It is possible that .9 is the top for your tune...why do you say it should be 1.0-1.1? It is also possible you have leaks.

 

their was no trouble codes in the computer. FVD claims that the car should pull 1.0 to 1.1 bar. where should i start looking for leaks ?
thanks for the help

 

pressure test at the turbos 30 psi.

 

FWIW, I had the FVD stage 2 software with exhaust for a few years and it only developed .9, just like yours. I had an occasional 1.0 spike for an instant - that's it. It was not until I upgraded to FVD stage 4 software and larger turbos that I saw 1.2-1.3 bar.

 

911stripper,

Out of curiosity how long has it been since your plugs were changed?

Try a mechanical guage first to see what you are REALLY getting. Then go from there.

 

Mark was a huge help ! it turns out that i have K24s not K16 hybrids. the problem is not solved yet, but at least i have some direction. Trying a real gage is a great idea too !

thanks everyone for all of the help.
