TurfBurn said:What is the setup? Is this an FI car with a stock P5 ECU or the like? If you are up in the 12+lbs of boost and with a stock ECU -17 isn't unreasonable.
its a turbo NON intercooled setup, only 5psi on an auto transmission. This makes me believe that those ECU comes with more advanced timing, and for just being non-intercooled makes things worst.
Im only pulling -12 @ 11psi on my car, compared that car was already pinging LOUD on the dyno with only 3psi...
