for a 2002 ls1 T\A with a4 tranny what is the best rev limit as of now mine is set at 6600 rpm and it seems to be good! many said it would not make any power but seat of me pants it feels like its pullin hard. Hypertech swears 6600 is the best setting and that much power is made till 6600 rpm, they alos say its tested and perfictly fine for somebody like me who is not tring to beat their car just enjoy it within its limitations. WHAT U ALL THINK AND WHY (so i can ask hypertech your reasons) I've found much contversy over this subject and am tring to come up with a consensus so i can figure out weather im beating my car or just opening it up to its full stock potential

Thanks john

In my own Opinion I would say that you are doing both! You are beating it and using it too it's full potential. You will make more power with changing the limit of the RPM's but also it is very hard on the car. It's different if you have major work or an upgraded tranny but the stock trans is going to make alot more heat from that setup. If it were my car i would just bring the RPM's to 6000. That's were they are now with 500+ RWHP.

have any suggestions for stock shift points

boomcase

My suggestions on my track performance, is this I tried many different shift point but every car is different, My car like the +1 on the 1 to 2 shift and the +2 on the 2 to 3 shift I gained about a half mph and almost a half tenth in 1/4 now i tried alot of combos that day and that worked the best and my rev limiter is set at 6400 but i leave my car in D and let it shift all day by itself. SO my suggestion is really you have to try and see what your car likes maybe it likes stock shift points maybe it likes alittle more. PS i do have a small torque converter in my car also.

Most stock cars peak in the high 5000 range (ie 5700 to 5800). I would shift at 6200 and set your rev limiter at 6400 for best results.

When mine was stock and used Hypertech, I set the rev limiter to 6600 and let it shift about 6300 or so.

Having that rev limiter kill your fuel uneccesarily (if it is shifting at a good point) can damage your car, too... AND be disappointing performance-wise.

An automatic is not in as much trouble with damaging the valve-train with over-revs as the M6's are.

Yea, the stock valve springs do suck.

Raising the limiter on stock springs is one of those "At your own risk" sort of things.

Some people never have problems. Me personally, I broke a stock spring in half at 20k on the stock limiter.

Good Luck,

Stock valvetrains achieve higher stress levels sooner in the RPM range than a more expensive(generally stronger) valvetrain. Fatigue in more expensive valvetrains occurs less over time, and during any given run because of better quality materials, machining, etc. With stock, I'd want to shift around 6200 max if you plant your right foot alot. Better quality springs and pushrods would allow regular shifting at 6800. <img border="0" alt="[driving]" title="" src="graemlins/gr_driving3.gif" />

sounds like 62 shifts with rev limit of 63 of 64 for me sound good??? and how can i tell what rpm im shifting at since the tach is notorously wrong is there a website that lists stock shift points for an a4 tranny with 3.42 gears (yes i know the a4 did no come with 3.42 stock but hypertech said they set it up with stock like settings. im just wondering what rpm that is if it is any help hypertech says that every mph i increase my 1-2 shift is 137 rpm every 2-3 shift is 73 rpm and every 1 mph on a 3-4 shift is45 rpm.

also thanks u all ive posted this in many different places and this is the one of the only ones where I got useful replies that seem sound and from knoldegeable people (with some exceptions: prostock also gave me a straight answer along with FEW others in other locations)
