Default speed density tune on the street?
Has anyone tried to tune a speed density 2 bar map from scratch on the street? I do have a wide band that works with hp tuners in the truck

My truck is awd and have not found a dyno that it fits on, too long of a wheel base

We are just retuning it on the maf for now with the cam, I think the easier way might be to put a 2wd trans in it for a day, lol

Street tuning in low traffic area's will be required even if you dyno tune it.

Not from complete scratch but close. 1st drives were like down the block, stop. Flash, drive a little further, new area's of the VE, watch the gauge. Stop the tune ETC... It would be a lot easier on a dyno but can be done.

If it's not on a Mustang Dyno it's hard to get the right load on it. It's also hard to compensate for underhood temps and various ect's as well as part throttle. Street tuning will be required.

Yes, I did exactly that. It's as easy as doing a MAF tune correctly in these days of 'auto tuning' macros, etc.

How does a SD tune act on the street? Do you have to retune with temp changes?
I'm thinking about doing it to mine.
