I don't personally use meth, but I was looking into it and alot of people were complaining about not getting an equal amount in each cylinder. mainly the #4 cyl. I was trying to find a kit that injected into each cylinder but had no luck.

Its called direct port and you can make one easy enough, all parts are available. I don't know if anyone makes a ready made kit either. I rely on water/meth allot to supplement my fuel needs and I haven't experienced any problems with leaning on #4 cylinder.
Direct injection is the way to go imo.

E*85 hands down. From what we found on our last engine the methanol does NOT disperse evenly to all the cylinders. IMO the only way to run methanol injection would be through a set of secondary injectors. We are now getting rid of the methanol.

What was your set up/levels?
I'm making 375whp on stock injectors if that isn't relying on it enough. But I'm in the process of ditching the progressive controller of the AEM kit becuase there is way to much lag time before injection starts to inject verses when its called upon and that's the dangerous part, its probably what helped caused your issue. I'm tired of brake boosting my injection to get it to respond when I want to go. So I am building a dual stage set up, the goal being that each stage injects 100% the split second the Hobbs switch sees the boost trigger point. Both stages will still be before the throttle body, depending on how well it works I may have room to up the boost again. I have considered one one of the two stages as a direct port, but that's allot more work and money if its not necessary.

When I pulled the motor, you could see the effects. Each cylinder was progressively worse.

Knowing what I know now with the AEM progressive controller, I would never use it on a set up with that kind of power. Your already at the threshold of what you can tune by conventional means, relying on a controller that cant respond to the demands is asking for trouble. Don't let this skew your thoughts on the effectiveness of water/meth injection, even in a single port pre TB scenario.
What CC Nozzle were you running? I drilled out my 550cc to aprox 700cc to deliver what I need at 11psi. All my cylinders show even distribution, yet I have a feeling I'm relying on my meth more then you were.

Why is that? Net power/performance you get over E85 I presume?
Meth injection
Ran 9's
700+whp
Pump gas
Minimal cost in fuel system
Better fuel economy
No motor issues
E85
Ran 10's
Ran out of injector so couldn't maximize my setup (I had old 1600cc)
Lost a rod bearing due to oil contamination
Horrible fuel economy
More investment in fuel system
Very inconsistent
Smells like what I think a bums nutsack would smell like.
