Although I'd be damn happy with a .70 on a stock car with tune.

Do you have a lead on the ELSD calibration Mike? I would like to see what is in there for sure.

$350 and your nearest dealer is all I know. But I would love to see someone with solid 60' numbers give this a try.

Pump gas?

Yes, 93 octane pump gas.

Very nice! I have been tempted to bring my car to the dealer for the rear end software upgrade. I do think they are charging way too much for it though.

I've always felt it would've ran a 10.8 that night if the supercharger hadn't been heat soaked. I actually made a pass to cool it down and test the starting line grip right before I ran the 10.94 with a 128.2 trap. It trapped 129.5 earlier that night with a 28 mph gain on the big end, but I couldn't get it off the line. I only had a 25.5 mph big end gain on my 10 second pass, so there was definitely more to be had. I've just not been fortunate enough to get that kind of air again.

I knew a tune only would make a big difference in these things. The fact they ran 10s in that high of a DA is very impressive!! It would take a tire to do it, but if you can get them to do 1.4 60s like should be possible, you're looking at mid 10s all day! Especially in good air. I had already been looking at buying hptuners to simply remove the torque management. Now you've really got me wanting to tune! Lol! I'm still planning to leave it stock until after this winter, just in case I can catch some good air again, but I think that'll be it. I'd like to at least have TM removed by next spring.

I guess because we took advantage of the good air, our times don't count. Racing on a cold track on street tires is not easy at all. I'm not minimizing what the op achieved with the tune only numbers, I too believe that with the tune only these cars should run mid 10s, but to discount what others have done with what they have to work with doesn't sit well with me. I don't think I'm that great of a driver, i just think that not many people race these cars much stock. I enjoy the challenge. I have no doubt that this is a 10.8 car bone stock in the right conditions.

I always bring you two up when someone posts something about this car doing 10’s, because you two did it first in stock form. There are some really good drivers that have not been able to crack 10’s on stock tune and tires. You could have given me 100 passes and I wouldn’t have cracked 10’s stock, that’s just being honest. We all recognize it isn’t easy at all, but the reason more people haven’t done it is because I think it requires three things:

1. A lot of patience
2. A lot of skill
3. Ideal conditions

I don't think Brett was implying your times don't count nor was he discrediting your achievement. That was a reply to the poster who said " At least 2 Stock tune cars have been that quick" without considering all the variables between the car posted in the OP and the ones who have done it on stock tune.

What Brett posted is what you can expect in more realistic conditions. Ya know 80+ degrees and 2300+ DA. Big difference between Summertime air and Fall air. Most tracks can't even get into negative DA without the track getting too cold. I know around here it takes about 50-55 degrees to hit 500da in the fall.

I hear ya. I think you're right. It seems most drag racers with these cars get antsy for mods and don't give themselves enough time to come across the conditions it takes to run 10s stock. I honestly can't believe no one has beat my time yet, because I knew there was a bit left on the table when I did it. I just knew you'd be one of them to do it. I'd really like to have another shot at it myself, but I don't think I can hold out any longer than this coming winter/spring.

I would replace skill with practice on your list, because I don't feel like I do anything special when it comes to driving the car, but I have put in lots of practice with a ton of trial and error. It mostly takes good DA and track prep. Which patience comes into play with all of that.

I'm pretty sure you're right, but I also get what Dave is saying. We've seen and heard it many times how "those were hero (money) runs, so those don't count". They usually don't say they don't count, they just imply they don't. Not just with ours, but with every stock fast list ever.

To add to what you're saying about the OP, the best I've ran in similar DA is 11.1 at 126 with the same 60' as the OP. So that shows the tune has added a bit of power. What I'm interested in seeing now, is how does it do with a drag tire? I would think that 1.5 and 1.4 60s should be possible. If so, you're looking at mid 10s even without cold air. I want!!

I don't think Brett was necessarily discrediting our times, at least I hope not, I really believe this is an honest 10 second car stock. I can't wait to see just how quick the tuned cars run in favorable conditions. I think I've exhausted the stock thing, I'm ready to make a move.

Any plans to tune the TCM with no other mods to see what gains are available there?
