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.

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.
