Bought a tubro kit off a friend of mine, kit is a garrett turbo, tial waste gate, hks blowoff, intercooler and piping. i ve had it for about a year (my previous car was stolen) and now i want to install it. My question is how much boost can i run on the stock fuel system. My buddy says i should be able to run 7 lbs no problem, but i dont want to blow my **** up.

 

if tuned correctly, not much on stock injectors.
