Do I pull to the rev limiter on the first pull in general? That depends. I almost always do load tuning up to a couple psi before doing a single pull. It dials in the off-boost fuel and gives me a very good idea of how much fuel the car is going to need at the lowest wastegate spring boost level. Most of the time the first pull has a very reasonable AFR and no hint of detonation on the stethoscope. If that is the case, I go until I feel the limiter to get the most information I can from the run. If I see the AFR going lean or hear anything more than the smallest ping of detonation on the first pull, the foot immediately comes off the gas.
