If I would run 42's, option B, heat exchanger, 2.8 pulley, ported blower, ported head, tuned with efi live would I need meth?

 

It wouldnt hurt, but I wouldnt say you need it. Why 42's with a 2.8? Might want to get some 60's. How do you like the EFILive tune?

 

yeah i'd get 60's over meth, you'll have to tune for both so

 

well i am running a 3.0 with stock injectors with only 93% IDC so I would think 42's would be enough and I like my tune

 

bump

 

you dont need it but i would get it anyways.. you do need 60's though

 

whats the idc with 42's and a 2.8?

 

spec is 80-85%, you'll be over for sure, with a tune not as much but you'll still be over 60's are jsut all around better

 

Im at 93% the guy that tuned my car says that im ok ive heard of other tuners tuning cars well over 100 idc and these aren't guys that just tune their own cars these are guys who make a living on just tuning

I want to know what idc would be with a 2.8 and 42's

 

honestly i dont know what it would be it depends

 

yeah I know, but hey thanks I might try 42's and have it tuned and if idc is to high then i'll just put 60's in it. im trying not to run meth i don't want to mess with it

 

i hear ya Area47 said he'd never tune anything less then a 2.9 with 42's cause it was a huge pain in the ass. if you do decide to run meth you could prob run the 42's cause the meth will actually richen up your a/f ratio. just dont want to see your injectors going static anyhow good luck with it all
