Mostly gonna be tuning my heavily modified lbz was just wondering how do figure out my limits and what are the different steps to take since i have changed my turbo to non vgt


Ideally you watch some of the worked examples first and start with a tune that's near stock power output. The 2006 Cummins and 2005 LLY examples have quite a few similarities. You'll have to disable some VGT turbo codes (whichever ones show up) on account of the turbo but on the whole, not have to dial in a VGT will make your first tuning adventure a bit easier because you'll only be able to control fueling parameters.

This forum is geared toward more specific questions which are bound to come up as you work through the process.
