My dyno numbres for one back my **** up, 30 RWHP in hotter weather isn't good enough? I will get track number no sweat, they won't be good ET times, but MPH will be better, I don't want to go ***** out on ET streets in 110 degree weather, just plain stupid, not worth it, won't net me my best ET. I went 113.5mph with my old cam, and I KNOW I am a lot quicker now with my X3. I can do low RPM, not sure what, but I can do 1200 I am sure, it's not that bad dude, if I couldn't do 1200 rpm I would have to take off from a light pretty high, but as it sits I can just ease off the clutch, no surging, bucking, stalling, etc, it's tuned very well and runs great!
As for my last cam, I can tell you I didn't like it, that's me, it didn't pull that hard, I could BARElY break the tires loose at the very top of the power bank in FIRST GEAR, and I have 4.11's, with the X3, as soon I as I hammer it, it's ******* blowing them away. So the X3 is a much better cam in my opinion over my last setup, makes more power and pulls a lot harder than the 224 did, so that's that.
I will get some track times as soon as I can I promise. I don't claim the X3 is the all mighty God cam out there, it's a great cam and I can't be more pleased with the switch.

There is no way in hell that the X3 runs all the way down to 1200rpm like stock. Absolutely not possible, considering the specs between that and stock. I'm not denying that the X3 hauls ***...its a huge cam...it should...but a great street cam, it is not. Sorry, but a cam that makes peak power near 7000rpm is not a "street cam" TR doesnt market the TREX as a street cam. They specifically say its a track duty cam. I think too many people are quick to jump on the "huge cam" bandwagon and just like the bragging rights. Again, I'm not picking on anyone, not an LG Hater, or trying to start anything...just adding something to this post.

You're telling me that your car doesnt buck or surge when you're on and off the gas at low rpm in lower gears? It never hunts for idle, or stalls with the A/C on at startup?
On the other hand my 1994 A4 Z-28 was to me the biggest PITA to drive and tune I have seen yet and I have helped a lot of people tune their LT1's. (I wanted a BIG cam for it) I had every conceivable problem you could have with a big cam. It would spit and sputter when you touched the gas at low RPM's, always had hesitation when you press the accelerator, constantly trying to find the idle while I was slamming the brakes through the floorboard trying to get it to stay stopped.
That what I mean about the difference in the drivability of the A4 vs M6 with these big cam profiles. I would assume if I did not have the ability to push the clutch in at lower RPM's I would have the problems you are describing as I almost swapped my 94 A4 with a M6 as I was getting real tired of all of the problems.
So to sum it up, would I recommend it to anyone without tuning? No
Can you drive it with a 6 speed without tuning? Yes but with obvious performance loss and low end fueling issues.
Would I recommend for an A4? Only if you had a 4400 stall or 4000 with extremely good tuning on a dyno and the street to clear up any driveability problems you may encounter.
Do you need a larger rear end gear? Yes,to make the low end more easier to start off and to make it feel like the stock cam or greater.

James I think you nailed it, from the way your car acted on start up and after 30 mins. of on & off ideling to check coolant level, etc. I think this cam is feasible as a DD to an "enthusist" and will be extremly livable with tuning.

Never been in a car with the T-Rex in it but i can vouch that the X3 is a good streetable cam
