I should have left it alone! 
Buy a shift kit??
Buy a shift kit?? I was wondering should I buy a shift kit? And is it cost alot to have someone install it? I was just wondering if that is something you even need or just a waste of money.

Thanx for the feedback

that one says you have to remove the valve body. What the hell is that and is that expensive to pay for someone to do this. As you can tell I dont need to be working on any car with my knowledge.

Well, i'm more than happy with my shift kit. I paid $93 for the kit from PBA and $50 to have it installed, it was money well spent. It's a good up grade in parts for these trannys, i'd do the kit over raising the line pressure any day of the week.

10 Camaros You Should Never Buy
Ls1 engine, 4l60e tranny, AJE Tubular K member, Hooker LT, baby cam, stall to 3400, open cut-outs to be cadillac quite, SFC, Air Lid(need a new one). Soon to come, Tranny cooler, 3.73 in a limited slip rear end, Leather seats,T-stat, remote start after a badly needed dyno tune.
-------------------------------------------------
If those are your mods the shift behavior can be worked on during your tune, and a Predator would be like throwing $400 in the garbage. There would be some merit in buying the predator if it is a shop that uses them as part of their dyno package, but otherwise the tune completely over-rules it.
However you look at it, if you want tire chirping shifts then you are looking at a shift kit. The stall converter softens your shifts up, and a shift kit can help restore some firmness.
However you want to look at it if those are really your mods you should just leave it alone and have the shifting tweaked during your dyno tune.

I just installed a shift kit two days ago. First time doing anything with the transmission, and it took about 13 hrs. Startede at like 2 I had to stop at about 10:30 because I small screen broke. Started at about 2 the next day and wwas finished by 4. If you can follow instructions you can do it. I found some online writeups from people who installed it that help me alot. I will post them if your going to attempt this yourself.
It's an age old debate, but the basics of it is that line pressures vary from transmission to transmission. Not only do they vary but the capacity of each individual transmission varies as well.
This is due to production tolerances - variations from transmission to transmission. So it is generally felt that just jacking up the line pressure is not a good idea. You can argue all day about "well, just xxxx much should be ok..." but it is what it is. You can choose to believe it or not.
Far as the tunability of a shift kit, I didn't mean to imply they HAD to be setup for tire chirping shifts... it's just usually when most people ask about them... that is what they are looking for.
