looking towards the trex...but still some questions i am really thinking about intalling the trex cam. the only question i have is about the idle. is it going to stall often and if so, will this be fixed with a tune. my mods are in the link in my signature if needed. thanks!!

yes, your car will stall without a tune. i was almost dead set on this cam myself until i talked to a guy with this cam and have read where a few others had massive idle tuning issues. i think it's a great cam, but just a hair too much for me. so i've settled on the x4 instead

well daily driver is not that big of a deal seeing as how i am in college and i drive like 10-15 miles a week...maybe a little more. i kinda figure im gonna need a tune on whatever cam i decide so i might as well go with the trex. the peak power is 3500-6700 RPM. that is a little late but well worth it once i get up there i would think. i looked at the tr230/224 but that is reverse split and i honestly dont quite know what that means. but the trex just seems so badass.

the 230/224 is a badass cam. my car put down 395/377, and DanZ had it before me and his car put down similar #'s w/ an automatic! For the size of the cam, you can't beat it. It sounds like i've got a beast in the engine too. And the best part, very little driveability was sacrificed w/ this cam compared to stock.
In terms of power difference the trex will make more power from about 4500-5000 and up .... but the tr230 will kick its *** throughout the rest of the rpm range. So for daily driving, and the occasional track run the 230>trex in my honest opinion. I have dyno graphs posted up in my cardomain page. Check those out, and then see if you can search for a trex graph and just look at how different the two hp curves are, and make a note of where the power/tq comes in for both of them. I'm running 3.42's w/ the tr230 w/o a problem. Most people will recomend you step up to 4.10's w/ the trex just b/c of it's lack of power in the lower rpm's.
Oh and a reverse split pattern just means that there is more intake duration than exhaust duration on the cam. The reason i picked this cam, was b/c i have dumped duals and LT's.... so in relation to my intake, my exhaust is VERY free flowing, and there for I would not need as much duration to let the cylinders exhaust.

every car is different plus you have a m6.like said more gearing for this cam.as far as d/d it thats another different story.try search and see what other people opinions.get a full tune.
good luck.

I just installed a TRex for a buddy a week ago, it idles like *** before it gets leaned out. It needs the idle hole in the throttle body to be opened up ever so slightly also to help idle. He made 422rw cam only through a full flowmaster catback...

yeah i figured as much with the trex idle. im sorta swaying towards the 230/224 but when i see he pulled 422rwhp with the trex that is awesome. i do have 4.10s so that would help a little. i guess im just gonna have to make the tough decision soon. i know both will be amazing so its really a win win situation. thanks for all the input guys

I ran the T-ReX on the stock tune with 3.42s for several months and never had a issue with the car stalling. Now, with 3.90s and a more accurate tune, the car is quite easy to drive.
So, before anyone with no experience with a T-ReX tells you it can't be done, I did it for a considerable amount of time with minimal problems. Having said that, the car is certainly more enjoyable to drive with a proper tune.

thats good to hear because i really want the trex. how was the idle without a tune. i would imagine it would have been pretty bad. i know that whatever cam i get i will be getting a tune with the installation and i already have 4.10s so that wont be a problem. the driveablility wasnt that bad? most everbody says it is horrible.
