How do they know how much boost?

[2g2ner86]

How does a place that tunes know how much boost you can run? Do you just say how much boost you would like to run, or do they just keep adding boost and tuning until they find a happy medium?

### thats part of tunning. you cant just turn it up and be happy. their is to much for your set up ya know, and when its to lean that to much ### you dont have enough fuel... To much boost . Their are a lot of things that tell them how much boost you can run.

If you have a giant turbo though, do they just assume you want to try to get it all even if it might be dangerous? (assuming they aren't leaning it out and causing knock)

I think it all depends on what you tell them you want, if you go into a shop and say tune her to the ragged edge, then that is what they are going to do. If you say give me a safe tune, that is what they will do. I think it all depends on the customer. No matter what though they should be watching your AFRs for sure and knock.

Has anybody used or heard of Backyard turbo in Stroudsburg PA? If so, how are they at tuning?

You should try your regional board.

There are a lot of variables as far as setting boost. I always look at the health of the motor and what upgrades it has to come up with a safe setting. So say a stock 7bolt bottom end with some arp headstuds thats been recently refreshed. I'd start at 24-26psi given the turbo/intercooler can do it.

Then when you get into tuning the car you can see if that will happen for you safely, intake temps, idc, afr, knock ect. All things that are affected by altitude/gas/setup. I should also add that if you aren't an experienced tuner there is no need to start tuning at those kind of boost levels. One bad adjustment/pull will end a stock shortblocks misery in these circumstances.

Sure it's not all DSMs, but it's all you could ask for in a regional forum... and more.
