546/547 webcams worth the money?

[dsmdeliveryboy]

I'm researching over cams and came across webcams and was wondering if anyone is running them and what their experience is with them. I was just looking at the 272/256 or 546/547 grind stage if people wanna get technical . I'm just running a 14b with 7cm housing right now, gonna go to a B16g soon though.

No one is running these??

I'm running them. Most people are afraid of them cause they had an issue with the first 2 batches but they replaced all of them for free. They are lumpy, I am at 3300ft and only see 8-9in @900rpm idle. On the 16g I can't feel any power falling off up to 7800rpm like the stock ones. My 16g spooled 200rpm sooner and less boost drop-off.

Are they able to be dropped in and ran without a tune? Because I can get them for pretty cheap right now I just don't know when I'll be able to be tuned for them. I know a lot of street cams your able to do that and you just don't feel the power gain till your tuned, but then again I heard these cams are really hard to get to idle.

If we ram speed density we would be screwed without a tune but at idle I see about 37hz on the maf. The maf should be able to compensate for the airflow changes kinda like bolt-ons. I don't remember exactly how far off my tune was when I dropped the cams in but I know it wasn't much cause I was rippin down the street staring at the WB and keeping my foot in it. Like I said, they are lumpy but they work well up top and you will find yourself wanting to run it to 8k. Just be ready to open the biss screw all the way and having a fast idle thermal valve might help too as mine is blocked.

I know someone selling a set right now for $250 shipped, I figured they would be a good bolt-on upgrade for the money. How are they in the low-end range? Do you sacrifice a little bit of low-end when you put these in?
