The main reason we remove the MAF is to go to the 2 BAR MAP sensor on Forced Induction.
If you are naturally aspirated there is "NO" reason to go to the 2 BAR MAP sensor and delete your MAF!
Your MAF is what tunes your Vette (Mass Air Flow sensor) as you drive, and a MAP (Manifold Absoloute Pressure sensor) reads in conjunction with it, we have on the stock Vettes a 1 BAR MAP sensor at the back of the manifold that works along with the MAF.
When a person goes to forced induction the MAF can run out of table thus you can delete the MAF and go to a 2 BAR or 3 BAR MAP(only certain years for a 3 BAR) sensor.
When you do remove the MAF, as in Forced Induction, it does send a code and this will not allow you to pass smog with it removed. So you would need to re-install it for smog purposes and then re-download you FI tune! (It's actually simple)
All I do is remove 2 clamps and stick my MAF back in and plug in the wire and go inside with the HP Tuners and download the "SMOG" tune with the MAF! Remember for smog purposes you never get into B@@ST when getting your Vette smogged
I hope this helps some
Thanks,Matt

Well. after playing with HP Tuners and getting rid of some of the issues. .Now the only code Im getting is the P0134. Any ideas as to what I can check.
