Is this right, Ive done atleast 3 good runs(freeware-VAG). APR91, no spare or muffler+rez, low tank, Im 150lbs. outside temp is cool. Perhaps someone could point me in the right direction as far as what to look for with uni/lemmi/vag. My S4 will never be faster than yours, so you have nothing to worry about.(only handful of S4s in 50 mile rad.) Thanks and have a good night.

 

You need to post more information than that for us to help you. take a look at your ignition timing angle, boost leak check it. What chip do you have? Look at your ignition timing retardation. There is a lot that needs to be seen before anything can be determined.

 

I've looked, but what are they suppose to be? My CFs(9s)MAF(250g/s)
Is it my 91oct APR chip? It seems to lose it up top. but I never hear any leaking. My lame *** is sitting here with freeware, for now, so Im limited on what blocks I can log.

 

9 is a little high, try pulling out a few degrees with lemmiwinks. Can you log your 02 sensors as well? I will post in an hour everything you need to look at.

 

This is the first car I mentioned. It is on 2.5 DP custom exhaust, meth injection and tune. That is it. This pull was on a tune not meant for meth and with 100 unleaded in the tank (mixed with 93 so it wasn't quite that high). Enjoy!

That helps, thanks. But what tuning was done on it? Otherwise mentioned, its stock?

My timing says BTDC but your numbers are + in the same amount. The engine load is much higher than mine.

I pulled up to 3deg of timing(-1.5, log 3 runs, -1.5, log 3 runs), But my CFs still hit 9s. I gotta go, so I'll log more while Im out and get back.

 

I am a dealer for VAST performance I install and tweak their tunes.

 

Ahh! I see. Its too bad Vast is too far away from me, but that wont stop me from exchanging my pipes for piggies next year.

My FATS are still 5.9. I added +1.5 deg timing, to see if I could measure anything, and logged 3 runs. Then my CFs went to 12s and my FATS went up .25secs. I cant help but think I cant pull anymore timing and that the car is pulling all it can due to the 91oct. Some day I'll test this by dumping some xylene and logging. DUH! I noticed my logs would sometimes say ATDC or BTDC. A funny thing too is I cant Pause Vag-com if my rpm is to high. Any way, its just a matter of time......and money.

 

Buy ECU explorer

 

Im not $THAT$ into tuning.
