The Haltech has a rev-limiter feature, so if you were to reflash your stock ecu to 10,000rpm you could adjust the limiter to wherever you liked below that. You could also build different limiters into your maps, for example a street limiter of 7000rpm and a race limiter of 8000rpm.

I currently have a '05 G35 6mt RevUp motor (NA) and UpRev's Osiris. I have the RPM limit raised to 7200 and the throttle body reprogrammed in Osiris. It sounds like that will still help out, even with the HalTech.
It sounds like it will always help out to have a flash with the HalTech (if you have a RevUp motor). My plan is to have UpRev make a map that is designed to work with the HalTech dyno tune. Sound like a good idea?

Only after they sent me the map, they told me they can get rid of whatever CEL I want - you just have to give them the code and they can essentially take it out of the stock ECU program. Pretty cool.

I hope to get my HalTech installed day after tomorrow along with my first dyno tune. I'm looking forward to it!

EDIT: Actually if you mess with the intake cam timing, then I believe the stock ECU will throw a code for that also cause it'll see that it's not where it should be. Another good reason to get Osiris to block that sort of stuff so that when you do get a code, you know it's something worth paying attention to. I don't have a revup so no experience with exhaust cam timing adjustments. My code for intake would only be thrown at high revs (which is where it was tweaked by Sharif to keep power from dropping - I have JWT S2 cams).

If you're not running test pipes, then it shouldn't be an issue. Codes being thrown aren't due to the Haltech (unless it's poorly tuned of course).

Nothing wrong with that, I just want to know which ones would be normally encountered in "normal" tuned haltech operation.

We have customers running over 8000rpm without a problem - here is one for example making nearly 700whp:

Hal, I think 617G was asking if the Haltech could eliminate the limp mode from occurring even if it's occurring now (without a Haltech).
If you have a NON-REVUP (04.5 and earlier), then you have a hard fuel cut rev limiter and that is completely overridden by the Haltech, so NO reflash is necessary to raise the rev limit. It is the throttle control that the Haltech leaves to the stock ECU. The 05+ models use the throttle to control the rev limit rather than fuel or ignition cut (so the Haltech does not override that).
I think even the 05+ non-revups have a soft limiter (throttle controlled), but I'm not 100% sure about that. To reiterate, if in your car, the throttle is used to control the rev limit then the current Haltech firmware will not be able to raise it. BUT it can LOWER IT on ALL CARS - using your choice of fuel or ignition cut
