I also got 26 mpg in the highway in my cammed LS2. Your tuner needs to adjust the DFCO settings and play with timing in the cruise area. My timing was in the low 30's and I didn't lean the crap out of it, but I had a different cam.

At steady cruise you aren't touching dfco.

Right, so I guess you'll have to find some hills to get better fuel mileage. Once I changed any air or fuel numbers the dic was off and mpg has to be calculated manually.

Hmmm.... Interesting... I average 19 driving mostly highway and all I have is a full exhaust lol

Well back to the OPs question. I will hopefully have dyno numbers this week with the the v3 with and without my cats.

My only advise for a cam... Is think abotu how big of a cam you need/want. And go a little bigger.

I went with a 226/230 specd cam from Pat G. And I love it. But wish it was a LITTLE bigger sometimes.

What I LOVE about this cam is there is NO loss of power in the mid to low ranges and a 30hp gain up top. I can post the dyno if you want.

My cam specs are 236/238 .601/.605 on 113. I love it and power still hits fairly low. It's aggressive at idle and loves the nitrous. At times I wish it was bigger but any bigger and it would move my powerband up to 3k plus so anywhere other than full throttle, it wouldn't be very useful. I like that it hits at 2100 and still pulls to 6800.

I think both you guys have great cams, when you have a big cam you sometimes wish it was smaller lol, i know i wish i would have went with a high 230s cam,i love the ms4 but the only reason i got it was because i got the whole kit brand new for 400, couldnt pass on it so thats what im sticking with, the only thing is the cam is only good as the supporting mods

MS4 is monster!! Are u still on stock heads?

I seriously considered that cam but piston to valve clearance would have been an issue and it's a 3600+ power range cam. It's a dyno queen for sure though and puts down big numbers!! I'd imagine it would be a pretty tough cam to daily though. How do u like it for drivability?

MS3 was the better choice of the two u listed IMO so good move. You'll love it.

MS4 will clear stock heads/pistons but barely. I spoke with TSP and they said to check to be sure but it will clear. And with a good tuner MS4 would be fine to daily. Other then trying to idle through parking lots in first gear at 5mph the cam in my mustang 234/246 drove like the cadillac and still made great tq.

I was told it was going to be dangerously close with stock heads. A little valve float and you'd smack a piston. How true that is im not 100% but thats what i was told. Just a little too close for my comfort. On the plus side, it chops/thumps hard and sounds ridiculous at idle and pulls like a freight train up top. The powerband for me just wouldn't have hit early enough. These cars are heavy and being a daily driver, I wanted something that would pull from lower in the rpm range. The MS4 is a dyno queen though and my absolute favorite for the sound at idle. It's a beasty stick!

I must say, my MS3 ain't got much under 3000 rpms, but I forget about that when I go wot. Lol

itsslow98

iTrader: (18)

Lol, whenever I have to merge into traffic or get somewhere fast i usually dont lug it around at 2k rpms anyways.

You think the MS3 doesnt have anything under 3k, drive a turbo car with 8.5:1 compression and a bigger turbo lol.

NeverSatisfied02

iTrader: (12)

Lol! But at 3k when that turbo is spooled... It's **** and get time... Lol

STAGEUP

I know what u mean. My syclone is a slug until the snail starts to spool. It's worse than my caddy with the ms3. Lol
