How can you check if they working right? If there a option on the PFC ? I am getting the car tuned next week and am second guessing myself. I have 1600 with the resistors. The car drives fine, but I really have not got on it. I want to wait untill it is tuned right.

 

put the stock ecu in it and see if it pulls a code?

 

well I know that when my secondaries did not work, as soon as the car hit boost it would stumble bad.

 

yeah that too

 

just wait to get it tuned, get it on the dyno, then you can be 100% sure.. no sense in blowing a motor on a hunch. If you are that worried. WAIT.

 

Same here, you'll definately know cause it will stumble. If the tuner has to continue adding duty cycle and its still lean is another indication.

 

thanks, I will have some backup resistors at the dyno just incase!
