I put down 284 stock with my A4 and after the predator tune I think it was 307. A/F is what your main problem is, if that # is correct. If so, I would not be driving much until you figure out the issue or may go boom. The only thing that ever goes off when I take mine off a dyno is the abs and goes off after a couple minutes. Need to check for any stored codes and I would try to find someone with a scanner.

Just curious, but in your first post you said the SES light came on.What codes,specifically,are/were you throwing?

Let's see...
Fuel pressure falling off at high RPM due to pump getting tired
Factory tuine a bit too lean (applies mostly to 98s) mine took nearly an extra 30% to be truly happy
Clogged injectors

RETARDED dyno operator; was there ANY datalogging for knock, spark retard, anything? And was that AF fantasized from narrowband sensor, or was a good wideband used? No dyno operator I know would run WOT at that AF.

Ok as for the SES light came on.. There were about 8 of them. He deleted them all..
Idk why but .. Ok As far as i could remember.
There was something about MAF.
Something about 02 sensor - This one was like 5 of them.
That's it as FAR as I can remember.

But my light just came back on again last night when I was racing, I would assume that the light only comes on when it gets really hot.
So i'm gonna go to autozone to have them check the code.

Could that be it?!?

Go strap your car to a dynojet then report back.

I was under the impression the 98 cars actually had richer factory tunes than normal.

If you have any codes involving the MAF, yo may want to look into getting the problem cause fixed, it does meter air coming into the engine, telling the PCM how much fuel to give the injectors.

Yes, I did clean the MAF yesterday, My car ran better but still hesitate.

So i am in the progress of doing my o2 sensors right now.

Also guys... My car is a 2000. Not 1998!!!!!!

He deleted all the MAF and o2 codes?! They are there for a reason, alot of people delete the rear o2's, but if he deleted something to do with the fronts that is your stumbling problem, although I'd imagine it would go way rich and not way lean. You need to get the tune flashed back to stock and start over, replace the MAF, replace the o2's (with GM originals, not Bosch or that crap you get from the autoparts store, those suck to tune with and generally fail quickly).

tell that jackass to put his bong aside and bring up those codes and post up what they are. we can help you a hell of a lot more knowing what codes are thrown rathr than jsut throwing money at an unknown problem.

yeah sounds like your tuner was an idoit, secondly bring all these post from people with nicer cars then him, and ask him why we all think he fudged up?!?

By Dyno Dynamic do you mean the do-it-yourself Dynamic Dyno PC software that you buy for $69.99 and supposedly determines horsepower and torque by detecting vehicle RPM through any 12V DC power socket (lighter socket) or did you put your car on a real roller dyno?

If so this is like trying to use a G-Tech Pro for hp.

abustiffy

No he means Dyno Dynamics. One of the most accurate tuning dynos, along with Dynapak, that doesnt spit out inflated Dynojet numbers. It sounds like the owner has alreaady answered his own questions with the codes. Those numbers are low even for a load bearing dyno. Address the issues and redyno with no codes. There is a simple calculation to get numbers closer to dynojet if numbers are what really matters. When it coes down to it, track times don't lie.

How's Your Fuel Pressure? Did You Check Injector Pulses? WITH YOUR SCANNER DID YOU CHECK O2'S ARE THEY ALL CLOSED LOOP? JUST ASKING

Wow that is really low

He DELETED sensors or ERASED codes?I assume he erased codes and since your SES came back on,that means they are there again and you should not be putting any more new parts on untill you find out the problem which we can probably help you with if you tell us the codes.Autozone can read them for you and write down the numbers please.

Maybe you have an LT1.

Just get a full tune-up, take it to a dynojet, and you should be fine.

Ouch!!! It seems like the owner is on the right track, however the genius dyno operator was out collecting a paycheck that day!!

thaigleshmk

Ok guys. I went to autozone today
Got my codes scanned:

P0410
P0137
P0157

Those codes have nothing to do with the 16.7:1 right?

Those codes didn't worry me much , b/c the previous owner has put an aftermarket catback on it(i assume). Therefore costs these codes to come on.

But what I am really worry about is that why is my car running so lean?
It's 16.7:1. This worries me the most right now.

Would changing the 02 sensors on the front do anything? Meaning that will it be running richer up top?. I don't want my car to blow up. This is my first American car. i don't want it to be my last. Help me out guys.
