I will be dynoing my car tomorrow and was wondering if the dyno run would should a boost/vacuum leak if there's one. I'm debating whether to take the car in for a boost leak test before the dyno run or not.


Thanks.

 

If your car is leaking boost then your AFRs will start to go rich. If you're hitting the dyno for tuning, make sure EVERYTHING is working up to spec before the tuning starts. You don't want to have your car tuned to a condition that will be different when the car is running right.

 

Thanks. It'll just be a dyno run and not dyno tuning.

I think that's what happen when I got custom dynoflashed, car may have had a leak or something must have not been running right.
