Do you have your vacuum lines hooked up how they are supposed to be? What are you boosting? What rev limiter isn't working? What is the CROM version?

i am holding 16 and spiking around 20, i got the top end rev limiter working dont think i did it right the first time, p/n rev dont work but i didn't expect it to, vacuum lines are not ran the stock way i ran them the way the wga said to run them, and i have version v.1r06

another ? what do i need to do to get an A/F ratio reading i tried to get it under OL_AIR_FUEL and it just showed 0.07 and never moves.

You need a wideband that supports analog output. Then you need to connect that to the trinity. The PID you are referring to is the FAR the PCM is trying to get, not actual.

I am assuming you are using the stock turbo. If that is the case, return all vacuum lines to stock, and get rid of that WGA and let the PCM control boost. You will be much happier with the results.

the stock waste gate works fine. I personally love it for the stock turbo. If someone really sits down with it on a dyno...you can make the way boost comes and goes a lot smoother and it will hold a good 16lbs to redline.

I agree the stock wga works very well but it has an underserved image problem because its,,"stock"

imo a good tune with a stock wga makes the switch to a $150 aftermarket wga only worth about $3. On a stock turbo, it might get you +.5-.75psi for the last 500rpm.

FTR: The most I've held on my stock wga was only about 15.0psi at 6000rpm. Usually its 14.3-15psi. Thats not too bad considering my $150 AGP wga has only held about 14.5psi.

ya i was right below 15 at 6k on the dyno. I had an FM WGA which was great but now I decided to throw the stocker back on and see what Don can do with that. Im having issues though with the boost not bein consistant. I may have a boost leak but I didnt find one last time I checked. Gotta look harder now..
