DSP Stage 3 tune - SRT Forums

**Philth** · 10-19-2009, 04:28 PM

Who here has used the 93 perf flash on their Stage 3 and liked it?

Currently, my AFRs are in the 10s, and I can only get 91 octane fuel.

I've used it and my findings are that it leaned my afr's out and gave me 2-3 more psi of boost. I am running the FM E3 47lb stage 3 turbo,FM wga and stage 3 pcm with no toys. It's easy to correct the tune though and that is what I have done.

Thanks for the input!

How many points did it lean you out?

Right about 1.6-1.8 I was told by mindmelt101 it was because of the added airflow of my 47lb wheel in my stage 3 turbo.

Wowsers. Okay I may try it again. I had a DSP way back when it was on (I think) CROM v11.

It was too lean (AFRs hovering around 13) but I think this may have been to my pump going south. Like posted in OP, AFRs are now in the 10s.

I also had some issues with changing when the fans came on. PCM would respond all weird and never could correct the issue. Even sent the file to Brian and he couldn't figure it out.

What CROM is it on now?

I don't know for sure but I haven't updated it since march of 09. The last update I did was to be able to adjust for every 1k. Mindmelt101 told me if I'm not having any issues then I wouldn't benefit from the new updates, then again I haven't spoke to him since march of this year.

CROM 19 and I would go back to stock, update your tool, then reload the new CROM file and start messing with the tune. This should fix all the little bugs with your current setup.

I'm using the DSP on my stage 3(stock wheel) i haven't been using the 93 performance tune but just played with the stock S3 tune and leaned it out a bit. Im gonna update to the latest crom soon so ill prob play around with it a little more.
