Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I ran a Sprint Booster with my engine when stock, and slightly modified and enjoyed the difference.
Leading evidence: 'Run sprint booster' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Run sprint booster' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Outcome without a verified action link
It's done correctly in fact I even went slightly larger diameter and it still not much difference.
So I'm looking at possibly doing a tune on the old 2001 C4. Car has 112K. I just had a bunch of items done at a local Indy (vario cam pads, chains, RMS, various pulleys, etc) and was thinking it would be fun to tune it for some minor burbles and maybe better drivability. It is a manual. I'm not looking for major power increases because well let's admit it, these cars just don't have a lot of power to begin with so it's a moot point anyway. I don't feel like spending a boat load of cash on one and wondering if there is anything anyone is using that they like and could recommend. Cobb, Softronic, etc........ I did a Softronic on my 991.1S and love it but just wondering if there is anything a little less expensive out there for this old dog?
There's not a lot that a tune will do for a stock M96.01,M96.02, M96.03.
There are not that many options for tuning, COBB does not tune for the base 996.
Softronic does tune for the base 996.
IMHO it's wasted money unless you've made some serious performance updates.
If it were me with a stock-ish 996, I'd look at the Sprint Booster, or other DBW throttle remap options.

During my engine rebuild, I gave the Sprint Booster to a friend with a stock 996 and he loves it.
Gotta agree with Tex.
Since the 996 is naturally aspirated and not a turbo like modern 911s, Caymans and Boxsters, software can help to improve e-throttle response and dial in the power band to a point, but you arent looking at the bells and whistles that you will get with a turbo car.
If you want gurgles the cheapest thing to do is get a gundo hack for sound and enhance your heal/toe skills.
No complaints on my end. I prefer a naturally aspirated car to a turbo.
I did the Fisker hack and it really doesn't make a difference in sound. In fact I think I'll open up the sides of the exhaust and cut out the baffles to help with sound.
It's done correctly in fact I even went slightly larger diameter and it still not much difference. I did the muffler delete and although sounds good between 2-4k, when you let off it sounds like a vacuum!
If you are looking for more sound, consider this for more more intake sound. Cheap and easy to do.
