To Lean? Need Help! Problem!

[NeOzz1]

DO NOT CROSS-POST. EVER.

OK i definetly have a problem. First I raced a car that has only run 15.1 or 15.2 tops ever and nothings has changed on it. I have 15 or 16 psi, a higflow cat, filter, and new plugs and wires. I am not positive but i think a should have beet him but I didn't, I was 2 or three cars behind him and it was at least a 1/4 run. Anyways thats the first problem, shouldn't I be faster then that? Ok second sometimes when I start my car it stutters and does not want to run for a bit till I rev it up a few times. could that be a cause of running lean maybe and could that also be why I am not as fats as expected? I am not sure how i could be running lean unless its because of the free mod of taking out your lower honeycomb. I am not sure whats goin on but i defitnetly need some questions answered so please help me!

Thanks,
Justin

You wouldn't happen to be venting your BOV to atmosphere, would you?

Pushin 16psi with a less restrictiv exhaust should put you better than a 15 in the 1/4.

But what did you launch like? Was it a good launch? Did you have wheel spin?

Sputterin during startup could be alot of things. You could have clogged injectors, causing lean symptoms.
Do you experance a miss fire? How old are your plug wires? There are alot of things that you have to asses before you can come up with a solution for being to slow.

wires are brand new and i didn't run at the quarter i raced someone that runs 15.1's and lost

So is the spark plugs changed too I'd imagine? If so look into that.

Even on this site a 90 TSi AWD with just intake is a 15 second car...so either its:
a) something is wrong with your car
b) this rival is lying to you
c) driver error

 

[NeOzz1]

1. yes plugs are new too
2. i have people i trust that know his times are true
3. i dont think it could have been a driver error because its auto so there is not much room for error

taking out the lower honeycomb will allow unmetered air through.

 

[NeOzz1]

so...

I think it's contributing to the problem. there may be other factors...
You need to find out whether you are actually running lean or not.

how do i go about doing that?
