irpq11, L99 Dyno results.

Now what? What's your next move?

I'm trying to save some money for exhaust, intake, and tuning. So the modding will soon begin.

Food for thought irpq11 .. if you know someone else w/ a camaro .. swap air filters and re-dyno or just do the swap and do some butt dyno comparisons to see if you think you pick up any ..

Hmmmm. I could break into the dealer and strip the IOM ss in the showroom.

It's not the money. It's the time away from the office. Things are almost impossible for her when I'm gone.

No mods and No tune. I will be keeping my factory warranty for now. I'm gonna have to take it to the dealer and ask them what the deal is with the mixture in my car. I haven't seen any numbers on anyone elses cars as far as fuel mixture to compare but the tuner said it is most certainly not right at all.

I say drop that bitch off at the dealer and rent a car...this is BS and youve done enough. The dyno dude says it sucks, you think it sucks, so the dealers gotta fix it.. good luck man.

Hopefully it will be an easy fix. They will most likely try a reflash of the stock tuning or a PCM swap. It will be interesting to see what they are willing to do.

Go to another dyno shop ... The 6l80e is going to eat up 2-3% more then a 4 speed auto ...

No they will usually read lean when they fail ... This is Cat Over Temp ... Based on the weather I would imagine that it was in full effect on the first pull ...

I do think that the 15% loss your dyno guy said is a bit optomistic though as it seems the norm for the manual cars is 15 - 16 % .. IF an auto is 17% that would put you around 330 hp at the wheels if it is a little more than 17% then it would be a bit lower. Yours appears to be around 21 - 22 % though ..

Keep us posted.

21-23 % is normal for 6L80e

SilverTurtle and I tested the stock 2010 Camaro Fram filter with an air compressor and it flowed less air than his DIRTY Fram filter from a 2002 LS1. This would affect the A6 cars more because of less direct control over RPM’s… Just a thought.

Thats an insane statment ... You check your air filter with an air compressor ?

This crowd as a whole is very number hungry but not to many people go to the track to prove what they accually gain or lost ... ? The weather is why the dyno has a correction factor ... And yet the smoothing was on 5 the highest you can make it ... Something was not right with there equipment .

Go to another dyno shop ...

i am waiting for the Vararam... but may buy a K&N filter in the meantime...

You might have made more power but you skewed every reading based on g/cyl in your ecm ... Don't do that again if you value your motor

Maybe 3-4 but that can also be a difference in dyno pulls all things being equal

There is no way in hell and OEM would tolerate that trust me it will not happen .. Ever ...

Sooooooo I'm guessing you think I should ............. uhhhh........... have my car Dynoed by someone different? lol

Ok. So if you had to make a guess. Would you say it's very likely my car is running fine, or do you think the guy that did my car is incompetant, or just has bad equipment?

Also, do you think the fuel mixture thing is reading wrong and my car is breathing better than that?

[PQ]

BTW all. For buying a BRAND NEW car, It sure is a pain in the ass to own right now.

If I go to another shop and the reading are not showing the car running right, then I'll need to go to ANOTHER shop.

[DanD]

I would see if the dealer can reflash the ecm, in case something is wrong with the stocktune. Otherwise... mine was about 11.5 AFR across the board and was 32xhp no up and downs on the AFR at all...

[camarotoofast]

I would get the dealer to reflash ecm before taking it to another dyno.

[Verio]

I wouldn't take it to another shop. You've got some baseline data to build off of. You've been rather patient with GM... and that's what's going to pay in the end.

[GMRULZ]

The numbers weren`t as low as I thought they would be at peak, but your a/f is really wacked especially on the first run as everyone else has stated. I agree w/ Matt it propbalby was in Cat over temp on the first pull. Other than going to another shop which would probably be a good thing, take the first graph to the dealer and see if they will either reflash or give you another pcm. Its most likely the culprit, as there have been some bad pcm or flashes in a few of the cars so far. When I dyno mine in about 2 weeks I`ll pist up my graph. It will be a dynojet also.

[slowerthanu]

You are stuck between a rock and a hard place. I never trust dynos that I have not personally seen so I can't help you there.

Some operators have no clue what the hell they are doing and others are really good but always booked, weather is horrible right now.

My wife drives this little turbo Jetta. That car is about a second slower in the 1/4 come summertime due to the tiny turbo and the horrid Utah heat.

You need to find a shop that is known for LSX cars and particularly the '10 Camaro with the 6L80E. They will be able to tell you right away if something is wrong based on other cars that they have run and driven.

All this forum can do for you is cause further confusion and continue to diagnose a problem that they cannot even put their hands on. There are tons of experts on this site but they cannot magically cure what they cannot see.

I hear you about your wife and time, can't help you there either.

Any chance your dealer (or your salesman) would come pick the car up from you and then bring it back? Seems like it would be pretty easy...salesman drives over a "loaner," drives yours back, etc.
