LS2 to LS3 MAF Base tuning
Working on the turbo setup for my 2005 C6, and Id like to switch it to a slot style MAF. I've already ordered the MAF, conversion harness and flange to weld into my cold side. The question is, will i need to create a whole new MAF table in HP tuners to be able to run the car? I will be having a professional tune the car, but will want the car to run well enough at idle/low rpm to move around and onto the trailer. Anywhere I could download a stock-ish 2008 corvette tune to get me going? Any tips are appreciated.

It also depends on the diameter of the pipe into which you are installing the new slot MAF element. Plan on it moving the actual MAF curve around and messing up how it runs initially. The good news is that it's an easy fix for any experienced calibrator. Honestly, if you're just trying to get it on the trailer, you may have better luck leaving the MAF unplugged until the tuner gets a chance to make the corrections for your particular hardware combo. Bad data can be worse than no data here, and it will just default to the speed density model when the MAF is missing. (Your tuner should ALSO tune this speed density model while he has it).
