Boost Numbers

What kind of boost numbers are you all seeing with stock tuning?

This video shows what mine is making on stock sticks and tuning.

My boost starts coming in really way too high so its not too usable for towing situations. I cruise about 1500-1700 at 60, and about 1900-2000 at 70. To get any real boost I've got to drop into 4th and hammer down and then it comes in great, but my egts get sky high even unloaded just pulling hills.

With the old tunes and in the 80HP setting I could hit 28 PSI.

That video is stock tunes and stock 90cc sticks.

I think that is one benefit of having an auto. My boost comes in good and quick and doesn't drop out too bad during shifts.

Keep in mind that that is being measured on the cold side of the intercooler. I'd have to guess that my actual numbers right off the turbo would be 3-5 PSI higher than those numbers since the boost will drop across the intercooler.

Need to install my ic but non it will make 17 or so. Tuned the 30lb boost gauge gets awfully close to zero on the wrong side if its really spinning.

With the manual, you need to be quick on the stick but there isn't any power loss. Try a short throw shifter to quicken you gear changes. It makes a huge difference.
