how much boost can you safely run with the stock tgp injectors? (motor stock, stock chip, just a mbc)

12 PSI is the max with the stock T25 turbo

Stock chip timing sucks ass and it flogs in the fuel under high load. Just putting a MBC on will not do too much other than make you feel like you are going faster.

You need chip work, air filter, and a tranny cooler if you are an auto.

The injectors won't be out run by the little T25. They will deliver with what ever boost you can get out of it with the stock fuel system.

Dave is about right. Anything over 12 is pretty useless. It will pump about 15 or 16 but you will go slower. Been there done that.

ok if the stock tgp injectors can handle 12 thats good.

I was actually asking this for a friend thats doing a 3.1 turbo in a beretta w/ 5spd.

thanks
