I picked up an ls7 maf sensor and a 4" maf housing from treadstone performance. make sure you get the honeycomb maf screen to help with tuning. This was the cheapest option I could find.

works well im guessing?

if my tuner is confident tuning without the honeycomb which he has done in the past for me (max effort GTP turbo) do i absolutley need it? anyone have one of these without the straightener???

how bout the rest of the stuff? no insight guys?

You really dont need a 4"..... probably wont see hardly any improvement... but I do have a 4" setup that I am going to put up for sale as I made my own setup to fit better into my personal setup...

as for the catch can, many styles out there and many are good.... I personally like the Rx cans.... but many others are good also...

good luck

If you haven't changed your plugs yet you may as well, you have what like 60-70,000 miles? They should be good for 100,000 - the AC delco OEM plugs are good quality but many people have used NGK iridiums as well. May as well change the wires too while you're at it - MSD

I don't think you need a larger MAF w/ your mods, but it wouldn't hurt...I think a FAST LSx manifold may give you some benefit at this point, maybe 1.85 rockers

I was thinking of adding 1.85's for some more lift

So get a catch can...
Get a different plug ...
And forget the maf..

Ive always had good luck with stock wires from gm if there was a diff in performance i might get the msd but ive never seen a dyno sooo ill stick with stock..

Any specific spark plug or should i just stick with gm again

I havent hooked it up yet. I did alot of reading on the hptuners and efilive forums, and people who dont run a screen have issues getting the tune dialed in. so im gonna run it to help me tune it.

Plugs, I went with AC Delco plug P/N 41-104, stock vette ZR1 and Z06 plugs. (Maryland Speed)

No need to upgrade your wires unless they are burnt IMO.

Is my lift calculation right?

Lift now with cam and stock rocks is :
610/617
Lift with 1.85
655/662

What spring would i need for that amount of lift?
