lb7 tunes

[Holland_Ass]

Can someone share some lb7 tunes for my 2003 duramax? I have it straight piped all the way back with an aftermarket intake and a bullydog gt programmer. If someone could point me in the right direction it would be appreciated!!

Dude, I'm in the exact same boat

So basically just tuning everything in the engine ourselfs with the calculator? and how smokey is it? both 50/50 and 40/60? im in it for the power more than econ.

Thanks for the reply!

Fuel and boost usually determines whether or not smoke is produced. And remember, smoke doesn't necessarily mean power is produced. It just means the AFR is really rich. Adding fuel and getting the timing dialed in is what makes power

[Holland_Ass]

can you adjust boost control on an lb7? and yeah I know smoke isn't very good i guess you could say

[ajamesbond007]

yes it is not hard. just lower or increase your desired boost values in the desired boost tables (however, you cannot exceed the maximum boost the turbo can produce without a bigger waste gate)

lower desired boost for slow response, less power, increased EGTS, and smoke production. the smoke will clear up once turbo spools up, regardless of how low you set the desired boost table (the nature of a waste gated turbo)

increase boost will yield quicker throttle response, less smoke production, lower EGTs (within reason), and more power.
