i have a 01 lightning and want a 4 pound pulley i have a chip exhaust and boost bypass and k and n. can i just put a pulley on and get my chip reburnt. do i need plugs or anything?

 

My stock plugs were OK with a 3 lber but when I upgraded to a 5lber, I went to a 'colder' plug. Extra boost can lead to detonation with the 'hot' OEM plugs.

You need NGK TR6s, at the least, and Denso IT22s would be even better.

For what its worth i am running denso IT 20's gapped at 0.40 ,with my 4# and chip, they are working fine so far..

 

JL sent me IT22's for my setup,luv them

 

I am running NGK-TR6 plugs gapped at .042. No problems at all.

I have 7000 miles on my truck with about 1000 of them with a 4lb pully. I have the stock plugs in right now and I have had no probs.

 

Stock plugs will work but, it would be to your benfit to run a slightly colder plug with the added boost. NGK's or Densos

I have a 4lber with TR5s and have no trouble, but to prevent a hundred "I told you so's" I'm going to install TR6s, someday soon. Already have 'em.

 

Running stock plugs with a 4lber is asking/begging for trouble, atleast thats what I think

 

Ran TR-5's in my '01 w/ a 5# lower.

usahooters runs a 6# lower w/ TR-5's and drives his truck to work everyday. He has had this combo now for over a year and not 1 problem.
