Very cool! But I wouldn't call it stock since it's been dyno-tuned.

Nice run...mineshaft air that night! The barometer was over 1024mb which is great. I ran at US41 a few years ago at an event...rained like a mofo all morning, and then stayed around 40 degrees the rest of the day...we never did get the car to hook up that weekend. I let my buddy make a pass because he didn't believe it was that slick, and he nearly bounced the car off the wall, and said "never again"...lol.

BTW: he posted it in the list thread here @ c5 (click here)

Not really... I mean what would you expect? His car I believe dynoed fairly low and was a very early 2010 car... it's likely that his stock tune would have only resulted in 13.3 or 13.2 in the 1/4 in those same conditions. Not everyone has results like Pave. In fact Paves results seem to be well above ordinary.

That's a real good run. Anyone that can run in the 12s with just a tune is doing great. A tune good for .2-.3 tenths or so. So his bone stock run would be about 13.0 - 13.1 (which would be in the top 5 fastest in this forum).

Why would just a tune not be stock? Come on, it's no different than in the old school days when you might rejet the carb. It's still stock!

L99 A6 (Tune)
reduces or deletes torque managment = faster track times.
adjusts shift firmness and shift points = faster times.
increases HP and Torque = faster track times.

With a tune, most L99s are showing an increase of 20-30 ft lbs of torque throughout the rpm range.

It's still a stock engine is my point. To me it's no different than tweeking an old school engine. For instance we would adjust timing, rejet carb and put a quick shift in the tranny. It was still stock.

yeah I don't consider cars with a tune bone stock. a tune would defeat the purpose of it being stock because it essentially "helps" the car out. bone stock to me is completely untouched without any added help.

I dunno...maybe cause this isn't your carb'd car? Tuned = NOT STOCK!

I still say tuned is stock. The engine has not been modified, just tweeked. Like I said before no different than rejetting a carb, adjust timing and so forth.

Yeah and that isn't stock either... you 'old school guys' are the reason why it's so hard for people to be honest.

"I bolted on nitrous, but I'm still stock"....

lol. I tied two jet engines to the rear of the camaro and simply put the car in neutral and I ran a 9.4! But the car is stock!

If you change anything that came from the factory it is no longer a stock car. Stock means from the factory. If your tune was adjusted post factory then it is not stock, im sorry.

Jetting a carb is not stock either, that isn't how the car originally came from the manufaturer. You are lightly (or bolt on) modified

Your comparing nitrous to tweeking a tune?

Umm..really? Do you know how many times we have to hear 'new bone stock record' and then you find out the car is modded all because it's accepted by some? It's a bunch of crap... stock = stock.. untouched, nothing changed, nothing removed from the car, etc.

Was a joke... but if you want to get all worked up over so be it.

I know this is unfathomable to folks who have known nothing but efi'd cars their entire life (I'm not point at anyone particular), but y'all are forgetting that the older cars don't have a computer doing all the *tuning* work for you...you actually had to get your hands dirty! Change altitude, change weather conditions, etc...think the same jetting for a car in Denver is safe for the same car at E-town? Hey, guess what, there's no friggin' computer to do the ditry work, so you're gonna have to pop the hood and turn a wrench just to keep it tuned up, or possibly even hurting soemthing. Points, plugs, cap/rotor, dwell/timing, jetting, valve lash...that was all routine *maintenance* back in the day...now, nearly everything on that list is handled by the ecm without the owner even having a clue it's being done.

Guy can call it stock all he wants. Fine with me. That's what he believes and thats a'okay! Each person has their own opinion. Mine below...

You still have to be able to competantly TUNE the ECM for maximum HP/TQ as well. Just because the computer can adjust for subtle changes its still has to be optimized for efficiency. How many "old school jets/points" guys you think can handle that? In my opinion all of them...IF they would just be honest with themselves and realize they don't know everything because they were simply born in the 50's. My pops is still talking 4 bolt mains, double pumpers, and 8-71. I just grinned and nodded. There is STILL alot to be learned from them and vice versa. Remember we learned from what the "old school jets/points" crowd left behind to teach us. Its time to pick up a book, google search, and catch up too folks!

LOL...last I checked, subtle changes > no changes! A carb & shaft distributor are stuck at where ever they're set, while the ecm (in closed loop) is constantly varying the fuel/timing...whatever the magic sensor tells it, it adjusts accordingly.

The generally accepted "stock" category per LS1tech and others is untouched just like it comes from the factory. That means no tune, no taking the spare tire and or seats out ect... Thats how we are able to compare the cars. So no, an a/m tune leaves the car no longer stock per LS1Tech and others guidelines.
