How many miles before getting a tune?

I think with the amount of money I have wrapped up in this engine I'm just a little overly paranoid and want to make sure everything goes good

Completely understandable! I actually like your idea of Amsoil break-in oil for the first 50, then conventional, then synthetic.

Seems like a good idea to me too. Plus I really can't justify driving out to Cottage Grove to return it so might as well use it lol

I agree with Steve, change that first oil out quickly. I think I went around 20 miles on mine too, then 100, then 500. At the 500 change I switched to synthetic. Just vary the RPM quite a bit and fully lift off the throttle at 3-4k so you pull a good vacuum.

Okay sounds good! You guys have been very helpful!

Good read here

I prefer when possible to seat rings on the dyno and immediately move to tuning.

Street cars= Idle/startup/check over, change oil.
Vac pulls (20 or so miles) Change oil

Begin tuning non high load stuff for a few hundred miles, change oil at 500 miles. Depending upon rough in mileage period, start tuning high load around 100-200miles.

Having it broken in on the dyno was another thing I have been thinking about because I have changed a few things from last year and it was never fully tuned last year and I definitely don't feel comfortable messing around with afrs or timing with aem. It just seems most people don't recommend breaking it in on the dyno.

Weather its on the dyno or on the street I just want to make sure it's done right

The car is tuned for wide open throttle so no reason to worry about any issues with the tune.

The car is not tuned for wide open throttle right now. That's part of the problem
