You want a little extra, thats why they make conservative OTS off the shelf tunes that do exactly that.
Different strokes for different folks. I stop at protune and bolt ons, others do E85, Nitrous and Injection.
We all have our desires and risk reward valuations. And for the record, the OTS stage 2 tune from Cobb was causing the same torque issues, so its just a matter of how aggressive you want the tune.
I can promise you my car is just as drivable as a stock car. Just as reliable but with better gas mileage and a whole lot faster...
I've started playing more with the Cobb data logging.
What's the take on the reported Torque values in Cobb? Just doing road passes vs dyno test, so curious on how they actually compare.
Yeah bro, you want to take any of this personally thats on you. I didnt have a problem with the OTS stage 2 in my car and doing all kinds of bolt ons and variations is not for me. I have sold enough cars in my time to know thats a huge losing proposition and a extremely limited pool to sell to.

Not accurate compared to an actual dyno from what I understand.
@PTS-BRG Hey bud just want to update every one again this time the delay is me as the weather is total crap here in SFL Mitch did send me a file well over a week ago so i apologize for not getting it done sooner. Also i have about 10 gallons of the good E85 in my garage. i will be using it this week if you know what i mean ; ) (ignite RED)
Also Mitch is the man ( i'm not his partner lol ) but he has been supper helpful with my car and several cars that i know of.
Dude, a week? Seriously? Give me the file and hold my beer. 🤣🤣. J/K.
Get out there and test.
For those that keep saying aggressive tuning and risk, you are wrong. Pro tuning brings your car closer to perfect fuelling. Thats safer not more dangerous for the engine.
Stoich is perfection. Lean is dangerous.
People lean out to save fuel. That is more aggessive and unsafe. Giving it all the fuel is wants is safer. So please stop saying the guys on the edge are aggressively tuning the car.
They are perfecting the tune. Making it faster, safer, more longevity. More consistsnt, more smooth, more driveable and a hell of a lot faster. It takes time snd a lot of work. But the end result is safer than your fuel starved factory tune. Its better for your engine as well. More cooling. We aren’t backyarders with a screw driver. Tweaking until it blows. Yes everyone has a storey of a ******** that did the wrong thing, screwed the boost up, went lean and bang. Thats not what PRO tuning is. That’s backyard BS.

Hes is saying everyone has their own limits on what they want and can afford and risk to do with respect to mods on any platform. And that he doesnt want to find out those limits himself and hes content with an OTS stage 1. Especially since he wont get any of the money back on mods. That is all personal preference. Some like gambling, some like drinking and other like hoes., most here love spending it on cars and mods for their cars. IMHO the chances of someone running a cookie cutter flash that simply 'works' are much much less than someone thats extracting every ounce of power and tq at grenading an engine. Even with it being perfected, materials are stressed exponentially thus way more stress which greatly reduces life.
Its not entirely true that you dont get your money back on mods. I have a friend who just picked up a preowned 991.2 and is looking for every possible aftermarket performance part he can find. Headers, Cats, Exhaust, DSC Module, Cobb AP, etc.. So, don't think there is no market for used performance parts, there is but people just dont want to pay close to retail for them.
If anyone is selling any performance parts for the 991.2 platform please PM me and I will put you in contact with my buddy.

@PTS-BRG@4 Point 0 Problem is fixed fellas no more shifting head aches on the 911.2. After several test last night the car is moving sweet and no problems car ran multiple 7.5 60-130 time without an issue.
It feels super strong and i think i can do better but with 100 degree ambient temps on a car without intercoolers lol we cant ask for more. I will try a 1/4 mile run today to see what she can trap.
I will add this was done on MS109 fuel 1/4 tank on a car with Soul Cat Deletes
Special thanks to @M Engineering Mitch you are the man! thank you for putting up with my bull**** and 10000000 text messages LOL!!!
You keep saying this, but Stoich for gasoline is 14.7 and that is LEAN when you're actually trying to make power.
At wide open throttle, you need to run rich to prevent detonation.
I think whoever explained to you what stoich is did it incorrectly, or at least your take away was.
Can a tuner jump in here?
From Summit racing: "It might sound like stoich is always the goal. That isn’t the case. Maximum power is usually found with a slightly rich mixture. Drivability is better at a cruise rpm with a slightly lean mixture. Idle tends to be better with a slightly lean mixture too but a big cam will idle better slightly rich."
