Is there a way to tell if you are running lean?

[Generation1JeY]

i'm gonna do some race gas tuning soon, and i plan on buying a datalogger before that to moniter knock and stuff like that when i turn up the boost. i just have a few questions:

1.With a stock fuel system(stock pump, injectors, no tuning device), when i turn the boost up to passed 17 will i start running really lean?

2. I know that i will have the datalogger to moniter knock and other stuff when i'm turning up the boost on the race gas, but how will i be able to tell if the motor is running too lean?

3. with 110 what would generally be the highest boost i would be able to run without running too lean or knocking too much on the stock fuel system?

i plan on upgrading my fuel system in the very soon future. 210lph RRE fuel pump w/ rewire kit, 620cc injectors, safc, 2g mas. i have all these items being held for me and i can get them, but i'm just short on money right now.

there are few ways you can tell your running lean...The best way is by using a data-logger..If you don't have one...You can pick one up for like 75 bucks or maybe even cheaper...dan

the best way to tell if you are lean is with a wideband

Also looking at your plug can help.. But The best way is a wideband.

Is 2 psi worth losing a motor over. Just play it safe until you have all the "supporting mods"
