WOT Fuel adjustment

Just had two quick questions. I've got a 2009 Chally R/T six speed with CAI, thermo, catch can, catless mids, E3 spark plugs, and resonator delete pipes. What would be a good starting point to set my WOT fuel ratios at? And does anyone reccomend messing with the spark? I'll be taking it to the drag strip in a few hours.

Add 10% fuel for the mids, and run the CAI tune.

have seen/read a lot of people have issues with them, like a lot of misfires and such....

fixed the problems and regained their performance by going back to stock plugs...

I did not know they made E-3s for the 5.7. I looked them up and got a message saying they did not make a plug for my car. That said these guys are correct. Get rid of them. The reason people have trouble with them is they retain to much heat at the electrode which will cause the mixture to fire prematurely (before the spark plug fires) The original plugs are copper clad for better heat dispersion...

Apologies for the double post there. Don't know how that happened.
The part no. for Hemi E-3 is 3.68.
So, I passed on the install. Now I have an expensive set of new plugs that don't sound like a good choice.
Do you have any experience or recommendations for plugs for a Hemi that make a difference?

Champion stock # 570 plugs are about 2 bucks each...

Do a search over on the LX forums and you'll see most everyone that tried the E3s started having misfires or the car just started running like crap at 1000 to 2000 miles...

Any issues with platnum or iridium plugs?

Best bet is to go with the factory plugs (champions) There is no advantage in the high dollar plugs its just a gimmick.

Platnum plugs are rated at 100k miles. Thats an advantage. Some cars have them stock so the manufacture can say the car has a 100k miles per tune up.

platinum plugs on a hemi is a no-no. guys that were using platinum plugs in hemis were having issues with the platinum coating on the electrode melting off then you might have the issue of the platinum chunk bouncing around the cylinder and a spark plug that isn't working properly. Copper plugs are the best way to go on these engines. I wouldn't put those stock champion plugs in any thing i own so I switched to NGK v power plugs
