Default Drill mod and nitrous?

I'm putting down about 400rwhp N/A and 470rwhp on the spray. When I run the car WOT N/A I have no problem shifting through the gears. When I spray WOT Its fine up to third. I usually have a problem getting it into 4th when I'm spraying. Will doing the "drill mod" solve this problem?

What will it hurt? Nothing. Do it, all it can do is help you.

Probably not. I never had a problem getting into fourth unless I tried to shift before I pressed down on the clutch far enough.

I press the clutch all the way in when I'm spraying or not spraying.

In the factory GM clutch line is an orifice that restricts the flow o fluid making the car easier to drive. The restriction also makes the clutch disengage slower. So you drill out the restriction, which makes the clutch disengage like it should. IMO, this restriction is is BS, so it needs to be drilled out.

Do you want your clutch to work properly and your trans. to live? If not, don't do the drill mod.

I did the drill mod today. The car binds up in gear N/A from 2-3. This is much worse than before. What a waste of time, and to boot my wife was bitching at me cause I was doing this all day instead of going to the lake with her and the boy.
