Removing MAF screen for Dry Shot I was reading some tech articals about using Dry Shot systems.... and most all of them said to remove the screen in the MAF because it cant read the proper charge and may go lean. here is a clip of the artical....
"For running a dry shot you should take the MAF screen out if you still have it. The MAF will report less air to the computer when on the bottle with it in than with it removed which will cause a leaner mixture when spraying. Why? I think it could be because the cold charge (remember, it reads velocity and temperature which both factor into how much O2 is in a given amount of air) doesn't hit the sensor wires in the MAF sensor as directly with the screen in. The more directly the wires are hit the more fuel is sent to the combustion chambers. "
Should I remove the screen in my LS1... please let me know ASAP. going to dyno the car on Sat and run at the track on Sunday.
HELP

Yes........
Easy to do.
1-Just unhook the MAF
2-Unbolt the front end that has the screen (Allen screws 4)
3-Using both thumbs and thick cloth, push it out from the inside.
It is not very tight, it will come right off. Also this way you keep it in one piece and can re-install it if you decide to go back N/A only or wet.

I've been wondering why my car seems to be the only one having trouble running a 100 shot without a tune. I'll have to try this nondestructive screen removal method and see what my results are.
Thanks...
Thanks...
I agree. On my v6 the screen froze over enough to get pulled into thirds (still loosely connected to each other) and go part way down the throttle body... That was when I started running over a 120 dry shot on it.
If the nitrous is cold enough to freeze the screen, it'd show up on the IAT, wouldn't it? I'm running Dave's Halo kit & my IAT only dropped about 10 degF in the 1/4. Maybe its the little 80-shot I run.
