Granted, it won't be perfect but I think on a bolt on car you can get by with just a MAF tune. A cam car I would do a ve tune no question but on a bolt on car I don't think it's mandatory.

    Agreed. The factory VE isn't so bad as long as you haven't altered the airflow dramatically.

    ported heads, and cam, but ive got the VE nailed down. resealed the intake tbe and now my a/f ratio holds between 13.8:1 and 16:1 on start up and idle, so now it sloud be tuneable. just need to take a ride this evening and do some logging

    PMed LPE about their 100mm MAF to see if it would be compatable with my 04 LPE CAI and Nick Williams 90mm TB. He responded no, it would take major modifications. I kind of guessed that but thought they might have tried the two together since they have a 04 GTO 3 to 5 pin connector for it.

    did he say what the issue was with it? Was it a wiring issue or something else? I would wonder if you'd run out of table at some point flowing that much air.

    He said "because of the diameter of the silicone tube at the MAF area."

    I wondered If the tube would have needed to be replaced with a larger one. In my reply I asked if they that used it with an 05/06... If so I wonder if I could used a tube from one. I'm right by Cleveland Pick A Part and am pretty sure I could get one cheap off a wreck.

    I wouldn't really call that major modifications if that's all it was. Check out this link. One of many but the first one I clicked. 100mm is 3.9" and 90mm is 3.5". They have a 4" to 3.5" reducer there that should work...it's 3" long so you'd have to fab up a little something to get it to your LPE box but shouldn't be too hard.

    Edit: they actually have a 45 degree bend hose and straight sticks although they're not cheap

    another choice, (the cheap option) that I'm using is a rubber sewer pipe adapter, they come in 3",4" and 3"-4". I laid the 3"-4" infront of the torpedo heater to get it soft, then streched the 3" end over my TB (stock size) ans slide the 4" end over my 4" intake tube

    This looks interesting. I may just give this a try.

    I ran the "fernco" set up on my f-body at one time. It works but it's not near as nice looking as the silicon stuff and it's a pain in the ass to work with everytime you take your intake tubing apart. I got a hose from baker and replaced it. If you shop around I'm sure you can find those silicon lengths cheaper than there. I saw a link here on the board a month or so ago.....I'll see if I can dig it back up.
