Thoughts on Injectors and Plugs
So, I'm in the process of getting a new engine and I'm currently running 3" JBP cold air intake, 2.7" pully on M62, 60lbs injectors, ngk iridium 2 step colder spark plugs, a vibrant headers downpipe high performance cat combo and a GMPP cat back exhaust, retune, MRZ front upper strut bar and phenolic spacer.
I want this setup to be problem free and I've read different setup and I'm curious with the 2.7" pulley what injectors and plugs other people would run with this setup. Let me know your thought without the smartass remarks.
Once everything is back together I'm meeting up with BennyHRR to get the right tune to support the finished setup.

Thanks man and I know you gave me input on the spark plugs also. Actually your latest thread is the reason I even made this. Some dude was like.... "anything smaller then 2.8" you should be using 80lbs injectors"....which made me say F*** I need to do this right if I'm going to continue!

James is right, If you were to run E85 You would need 80's on a 2.7" pulley. Our local pumps have 10% ethanol in the blend, so barely anything in there. 60's are fine for now with your 2.7" Pulley, Ask your tuner to show you how much gas is being used during a pull, ud be surprised that its not even close to being maxed out

Copper Spark Plugs
Copper spark plugs are generally considered to have the best performance of any spark plug type. This is potentially different from what advertising companies suggest, but the other metals are, unfortunately, not as conductive in general as copper is. Platinum and iridium plugs are more likely to overheat, which causes damage to the plug components and can compromise the delivery of the spark to the engine block.
Platinum and Iridium Plugs
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity. Platinum has good longevity and the worst performance. Iridium has good longevity and a performance that is decent, which is why iridium plugs tend to be more expensive than any other type. Still, the difference between these plugs in terms of overall quality is minimal, as there is a trade off for each.
Most copper plugs need to be changed every 20,000 miles or so. Platinum and iridium plugs can often go for twice that before they require changing, but the overall performance will not be as good and you may have to deal with overheating of the plugs. This is potentially not worth the added cost of both platinum and iridium spark plugs, although the decision will depend upon your preference.

My 07 LSJ has always seemed to run real good on step 1 colder NGK copper plugs. Now that I switched to the 2 steps colder with my recent mods I'm not so sure I should have changed.
I'm having idling issues like most people have talked about but I also just installed 50 lb injectors, LS4 throttle body 3" ZZP intake with a new tune. My throttle body is new but has been setting for quite some time till I bought the rest of the parts.
I've tried platinum and iridium plugs and always found that the car didn't run good with them so I always switched back to NGK step 1 colder plugs (of course I use to be GM Stage 2). I wouldn't suggest any other plugs besides the step 1 colder copper plugs for most LSJ's. There's always exceptions though.
