[RocCitySlayer]

check the maf you have on the maf comp screen.

Right now its set on stock maf, that is what is currently installed on the car. Is that all I would have to change? Or would I need to retune it for the evo8 maf?

Pick the maf have on link, and adjust accordingly, make changes as you need since you have different maf now.

how much more does the Evo 8 maf flows over the 2G version? 20-25%?

Pick the new MAF template and play with the lower end of the MAFComp table

Is there a noticable difference in using a 2g maf and swapping in an evo 8?

Up to a maximum of 32% more flow that the 2G but I see guys using injectors roughly 25% bigger than stock [450cc to 550/560cc]when using the Evo 8 MAF on a 2G

Right now I have an hx35 with fic 1050cc injectors. And the 2g maf? Would I benefit?

The Evo 8 MAS reports a lower frequency per same air mass flow, it can accurately report higher frequencies than a 2G MAS and it is also a lower restriction to flow. From what I understand about MAF sensors, the difference between the Evo 8 MAS response curve and the 2G MAS curve should vary enough that it would not be accurate to compensate with just a global fueling change. However, with that said, I've seen posts by a certain well known old school chip burner stating that he simply used a flat 25% global change to compensate for the newer MAS on a 2G and a 67% global change to compensate on a 1G. I can't personally testify as to how well this works. I've had a really nice looking Evo 8 MAS just sitting in a box here for about 3 years that I have yet to install and tune with on a DSM.

Edit: This shows the 3G #482 MAS, but the Evo 8 MAS is supposedly the same:

you will not benifit and will need to be retuned.
