Hey, I just got my VF34 and supporting mods installed in my 05 WRX. My question is with the Cobb Accessport and using the VF34 93 octane map how much PSI should my car be running? When I pushed it, it looked like 13 lbs was the highest the gauge went. I thought it would have been much more boost than that considering how much more powerful the car is. Is 13lbs the correct PSI or should it be higher than that? I also have the factory boost gauge and it read .9 bar max. Is that what is should read or is something wrong?

Thanks,
Chip

 

how long have you the set up on your car? on my '03 i ran 17 psi. if you read the map notes on cobbs site it i believe it says you should run 16.5 +/- 0.5 psi.

 

I have had this setup on my car for about a week now. I used the AP and read the live boost pressure and in the book it says the AP max's out at 18.3 PSI. Well when I used the live boost function my car hit the 18.3 mark. I am taking my car over my buddies house tonight and he is going to look at the lines to the gauges to see if that is where the problem is. He said he would even re-route the lines if he has to, so I get a more accurate reading.
