Trying to tune to ECU for more boost

Reply #15 –
Thanks for the suggestions!

btw I installed the narrowband afr gauge at 15psi it's sitting right in between ideal and rich which is great! I was afraid I was running lean.

18 PSI tomorrow. Ordering Snow performance stage II Meth Injection tomorrow also. (from summit racing)

Dyno run to follow in the near future.

I was able to beat a hemi charger today at 15 psi. From both a pull and a dig. That was highly unexpected, but I am pretty happy about it.

the shop said I was when I was on the dyno...

the only thing I can guess is that the bad O2 sensor was throwing out bogus numbers.

I call BS. There's absolutely no reason for you to run lean on stock boost... they just want You to pay them to work on it. Ford tuned these things to run way rich. The only way to run lean really is if your pump is dying, and then it would be pretty obvious.

The o2 isn't even used under boost, so I would say that's not it..
 Chances are your car is fine.

The o2 sensor has ZERO function at WOT, if you were running lean, probably have a F/P regulator problem or other fuel system issue...

thanks for the advice! my air fuel ratio seems good at WOT so I dunno what they were talking about.

A little update

I made 184 RWHP and 247 RWTQ on the dyno at 16psi

Turned the boost down a bit just to be safe.

For comparison a bone stock STI made 216 AWHP and 230 AWTQ right after me

You might think WHAT?! an STI reading that low?!

two reasons

at near 7000 feet altitude you take 15% or more HP loss on a boosted car 25% for N/A

also, their dyno reads low

both of those numbers are uncorrected, so I am not really sure what my actual horsepower / torque is. I would be especially happy to know what it is at sea level and at 18psi haha.

Now, on to my question.

I just purchased a wideband from innovative motorsports.  I want to upgrade / get rid of the VAM and was wondering what my alternatives are?

What air meters do you performance gurus use?
