Re: boost

The boost target in the stock chip 13.8psi, but our truck don't have solid boost control. Over a 1/4 mile run its look a roller coaster ride, usually varies about +/- 1 psi or so.

Re: boost

If I run more than 15lbs of boost, what will happen? what do I need to be able to run higher boost? I'm in the process of rebuilding my motor and would like to run 18-20lbs of boost with a 20g turbo.

Re: boost

to run more than 15psi properly you need a 3 bar map sensor and proper tuning on your ecm. Running that much boost on pump gas can be a problem unless you use alky injection or switch to better fuel. Check out www.alkycontrol.com. They have an awesome system that we use lots of and you can run big boost on 91-93 octane pump gas no problem. We have trucks and cars running 25psi on pump gas with 20 degrees of timing and no knock.

Hope this helps
