How many miles before getting a tune?

[4seasons69]

Alrighty this is my first brand new engine. What I'm wondering is those of you who have broken in new engines how many miles did you put on it before you got a good tune and started having fun with the car?

The break in procedure that map gave says after 500 miles it should be ready for normal driving. Then it says I can switch to synthetic oil at 1500 miles.

So would I be good to go at 500 miles to get a tune and crank the boost up or should I wait till 1500 when I can switch to synthetic oil? What do you guys do with your engines? Thanks!

I think we put 100 miles at most on Vassil's car before we took it to Shane.

Per Ron, when talking about my car.

-Don't be afraid to get on it.
-Use regular oil for the first tank of gas
- Change the oil, inspect the oil, refill using regular oil
- Run for 1000 miles using regular oil, then tune and change the oil with regular again
- Run for 3000 miles, then change back to synthetic
*Using regular because synthetic is too viscous, and doesn't allow the rings to rub enough on new pistons*

You should be afraid to get on it, if you don't already have a tune for your exact setup. The last thing you want is detonation on a new motor that hasn't has time to seat the rings yet.

Hmmm does he do a lot of street driving? There seems to be a lot of controversy on how to break in an engine. I have heard a lot of people say break it in how you're going to drive it. I'm shooting at least close to a similar power level as him so idk how important mileage is to higher hp engines

That's good info! As for the oil I have enough amsoil break in oil for the first 1500 miles

This is true. This is also kind of why im asking how long I should go before I get a tune because I want it tuned as soon as possible

Did street driving before switching to all slicks... He is also on E98. A lot less chance for detonation.

It might be a good idea to have Shane or Ron give your car a break in tune. Low boost, but still correct timing, FTA ratios, etc. That way to don't blow it up. Then break it in for like 1000 miles, and retune it.

Shane brings up a good point of clarification. My car is tuned, just not fully. So, I can get on it a little.

That is a good idea but the problem with that is low boost on my car with my wastegate setup and a gt42 is like 36psi lol. So i want to get it broken in enough with the gt42 then switch to a pte 6766 and get it tuned

You don't need to boost it to break it in. NA cars don't have boost and they break-in great. You want to pull some really high vacuum as much as possible to help with seating and vary your RPMs and loads.
