Why do people adjust boost depending on their driving conditions? I see folks say they run 7psi around town and 20psi (or whatever) at the track. Why not just set it and forget it? If you have your car tuned for 20psi and don't boost it around town, then it's no different than if you had it tuned for 7psi. I don't get it. My car is tuned for 10-11psi right now and that's as high as I can go before fuel cut (I'm on a stock ecu, no piggy back or FCD) -- so I just leave it regardless of how I drive it. Why would I mess with it and reduce boost for just "driving around town"?
Adjusting boost?

I don't change it much. My standalone was tuned @ 14PSI and that's what I run the majority of the time. Yeah every now and then I'll crank the boost up a couple pounds but I tend not to as my stock twins are on their way out. But once I go single I'm just gonna set and forget it and just take it easy in the rain and snow (I daily drive my car).

LMAO! That's the whole purpose of boost!

I can think of a few reasons. Fuel economy, for one. After all, the limit set by the boost controller determines the maximum rate at which the car can consume fuel.
There's also the whole "turbo bite" thing, which may not be the experience that you want on the highway.
Plus there are always the police. Lower boost setting = less temptation = fewer conversations on the roadside with the local constabulary.

So, drive the Miata and worry about everyone else trying to kill you.Poodles;1862670 said:Because it's nice to drive a car that isn't trying to kill you
Seems like a good enough reason to me...Dan_Gyoba;1862714 said:
Honestly, I'll admit that higher boost pressures have taught me to be a better driver. Smoother on the throttle, more mindful of WHERE I boost, and have learned to drive the car sideways without getting scared in the dry. Better to build confidence in this than suddenly realize your car is (as Poodles puts it), Trying to kill you.
Even if I'm a better driver for it, I can STILL be a better driver without that turbo bite...
That said, I leave the Supra at 15 lbs all the time.

Me and everyone else i know just leaves it. Varying from a 7m on 9 pounds to a sc300 on 35 psi. We dont adjust boost, just our right foot.

Early morning Logging run 25+ psi with a GT3540R and slightly damp/misty road, log shows the "Ohhh SHIT" moment where it burst into wheelspin at 100+ Mph rollon...
(I think wee came out)
This was before my DBW Trac setup, I also have logs showing wheelspin over 100mph on a bone dry road so being able to adjust boost for the conditions can be a good thing, I know you can always pedal it but sometimes you're NOT Lewis Hamilton or Mark Webber..
