Curt, can you tweak my tune to limit throttle % by speed? M6

If it's just a pulley change $150. Otherwise kind of depends on changes

I've done one redeye flex. Went well. Would like to do another to confirm although I'm pretty confident in it at this point.
Okay thanks Curt. I'll check back with you later when you've done some more flex tunes on Redeyes. Appreciate the reply.

This will be tough in a 6 speed car. My buddy Chad did just about everything to his 6 speed and I think his best ever was a 10.1 at like 143MPH (something like that). You'll find you hit a point where you have all the power you need but can't get it to the ground effectively. Chad hit that point a couple weeks back and is now in selling the 6 speed and getting an auto. Another friend went to the track with us last weekend and at the end of the day he's now decided to also sell the 6 speed and get an auto. I think watching us auto guys make minimal changes and run 9s was a bit demoralizing as well.

Probably not what you wanna hear, but I've personally been there done that and it seems most folks end up at the same place eventually. I'd say consistent mid 10s are doable in a 6 speed though. Would love to see you prove me wrong though so best of luck with the car.
I've seen some of Chad's driving (videos), he's a great manual driver! Considering the 6M, he's done great work with it!

I had a 15' M6 for a bit and I'm so glad I got rid of it. Even driving around town I enjoy my A8 much much more, and drive it more because it's more fun to drive to me. The 6M has awful stock gearing for racing. I watched as A8 drivers ran much faster with a lot less effort. M6 guys gotta make more power to go as quick. Hell even some of the A8 scat packs were running damn near as fast as me. Felt like I was fighting with one arm tied behind my back! After driving my A8 Redeye it's like a whole different car, the A8 is snappy and just plain moves out! I would never even consider getting a M6 again. Didn't enjoy the notchy shifts, and terrible gearing. Plus the market for performance seems to cater more towards A8s.

Yes, agree, stock M6 gearing sucks for getting out of the hole. I changed to a 2.98, 2.10, 1,43 Tranzilla and with the 3.73 now has almost the same low end final drive as the A8 but without torque control the A8 can be tweaked to. The 2.98 2.10 really woke the car up, I’m pulling over a G on the street now from .65 avg but now spinning is very easy and happens so fast I’m just not quick enough to not loose time over it. I love the way the A8 sounds and pulls but have to test this new combo out at least. I’ve already ran a 10.734 on stock gearing but that was a fluke slipped the clutch just right, hit every gear perfect run, never hit a 10 again afterwards, I’m 11.1-11.3 all day round and round just can’t get the 60 ft down. I’m hoping the New 17” rears and tired along with the 2.98 put me in the 1.5’s 60 ft then consistent high 10’s should happen. Some practice and tweaks mid tens and by seasons end 10.0xx and I’d be happy with my M6, for a while at least lol

Yeah, if ultimate ETs are your goal and you want to avoid the struggle/commitment - definitely don't use an M6 car. 10.99 is my ambitous goal.
10.99 is possible, I’ve done 10.734, only once though lol

Yeah I thought about changing the gearing on my M6, then decided to go A8 instead. Ran a best of 11.74@120mph (1.77 60ft) 3500DA in the M6. Bought the A8 Redeye and ran my best (first time out) of 10.46@130mph at 1900DA (Both cars stock on tire). After running 11s, I was just hoping for a high 10 with my Redeye, I was shocked to nail a mid 10, and happy as hell! I didn't have the time to try a slick, but I heard that the M6 cars usually do better with slicks vs drag radials.

Now I'm here looking for low 10s in mediocre DA and high 9s in great DA, just from an E85 tune. Getting to that point with my M6 would have taken much more effort. I don't have to push my car nearly as hard to get there. Makes me feel better about that, when I beat on it, lol.

I applaud your effort with the M6. Most who own the M6 don't seem to race them, but rather keep them stock. Good luck with your goals!
