Porting and descreening MAF
Porting and descreening MAF If I were to do this on a 2000 C5 what would the side affects be if any? I did it on my 98 Z28 and it didnt do anything but gain and I had no driveability issues. I want to hear it from someone who has actually done it on their car. I dont want to hear someone repeat things that they have heard. I keep getting mixed signals from members as some say good and some say bad but I can not tell if its simply word of mouth or from their own experience. Thank you. 
if you are a M6 you will proabbly be fine, as the auto's don't really like the descreen until you take it to a tuner for some reason.
I have taken mine out for more than a year now with no problems. I also couldn't tell the difference.
Ask your tuner and see what he likes to work with the best.

I've been running my car with Thunder Racing ported MAF ends for a while now and I haven't had anything bad happen to me. It's on my 98 z28 M6. Once in a while it'll throw a code saying too lean but it isn't anything that can kill the engine. I just have to make sure it is installed correctly and delete the code. It won't come back unless I unplug the sensor and reinstall it.

I descreened my MAF while tuning on the dyno just to see what it would do. It ended up leaning my car out by a full point. It did gain like 5hp to the wheels but thats after he adjusted the fuel table. Definately wouldnt suggest doing this if you plan on driving it before tuning.
Obviously its not good for the engine if the engineers of the car decided to make a code to tell you that the car is running lean. Granted I am not a fan of engineers (im a helicopter mechanic) but some of the things they do is actually for a reason.

descreened and it ran lean... though my situation i advise against it. and their is no noticable gains... its all in everyone's head. it's funny people think that they can feel a 5rwhp difference

u are just asking for trouble porting and polishing a maf, u may screw up something and eventually would go back to stock, I took the screen out of mine and it was hard to tune and had to eventually buy another stock one. The tuner also told that messing with the maf will eventuall eat uo 3rd and 4th gear. Thats y u see ported mafs so cheap everywhere like ebay

I removed the screen on my old Z (which was a daily driver). I had no problems with the car on the road, but I also had no dyno info to see how my A/F ration etc. was changed.
But honestly I never noticed any kind of a gain but did hear plenty of horror stories, so I'm just going to leave the one in my SS alone.

Oh and your car runs better with the maf anyway and the power difference is negligible. Especially when you are well below 600hp which I know people have used the stock maf up to.
Until the maf becomes a reasonable restriction then sd is not worth it. Especially if you have a change in season coming up. Your car will run shitty unless you get another tune to fix it. Most good tuners can forsee this and prepare you a decent tune for summer/winter that can be flashed in very quickly.

the only drama i have with changes of season is when it rains i have no traction, not that its hard to break traction in the dry though
id say the majority of people over here go mafless

Then they bring it out and instead of being 90 out is 32 and the car is like wtf is this ****.
Probably wouldn't matter much if you don't have that big of a difference in the seasons.

I'm not sure how $900 translates from Aussie monies.
