The AFR's are listed on the bottom black line. All was running very rich. Found nothing lean. A tune can lean out the fuel and and adjust other tables and make more power.

The torque will also come up on the header back as well after a tune.

Do you guys have plans to get tuning software anytime in the near future?

In the works yes..

This was my dream car when I was like 6 years old, I still remember the artcile in my dad's car magazine about it. Fuck me, I would kill to drive one. I had an NA AW11 as well, loved it so much.

PM'ed you with quote request for full system including pulley and takeda intake

Is it too much to ask to get a dyno run with just the CatBack and Pully???

To mee this combo seems like it might just be the best bang for the buck and still keep the car smogg legal.

I would like to see this combo as well. Cat back+pulley and Header-back+pulley. This is what I will most likely go with at first. Adding the tune and the head further down the road maybe.

in regards to an earlier post about inirtial dyno's "guessing" at HP numbers...this stuff makes my blood boil, do you even understand what horsepower is? it is a measure of work done vs time, accelerating a known mass is the most direct way to measure that. if anything, a load bearing dyno is a guess, it relies on calibrations to approximate the load being generated, which varies greatly based on type of resistance/load etc.

Out of respect for the OP, I'd prefer to have this discussion in a different thread about dynos. When I start the official dyno database thread, maybe that would be a good place to discuss it.

Here is one of the Dyno runs. I think it's the second run with the full exhaust and pulley.<object width="400" height="240" ><param name="allowfullscreen" value="true" /><param name="movie" value="http://www.facebook.com/v/451566588208184" /><embed src="http://www.facebook.com/v/451566588208184" type="application/x-shockwave-flash" allowfullscreen="true" width="400" height="240"></embed></object>

How does the car fell overall EZ? Im use to putting N/A bolton's on my old S2k and couldnt really tell much difference. Is the drivability and overall performance noticable while daily driving as it looks on paper?

please people if you don't know what you are talking about don't "school" people,


and vivid Great job on the break down but

1. don't feed the trolls

2. shame on you for feeding the poor understanding of dynos, Jason may be the nicest guy in the world but when he is "driving on the dyno" his only function in life should be that of a brick in relation to the throttle pedal...give credit where it is due, and accept it under the same circumstances.

VERY GOOD POST! THANK YOU!

That is all well and good however.

1.) the mods will delete if they see a problem (and there is no problem with what/how I posted)

2.) it is relevant here. (unlike your comment) last thing we need is for people to start bench racing their dyno operators...ala....my dyno operator makes smoother plots than your dyno operator, or XXXsmitty at XYZ dyno sucks he never gets the same HP as Johnny57...we have alot of noobs here, I'd prefer if they had the ability to sort the flyshit from the pepper and didn't get led astray.

The acceleration and throttle response have improved. I haven't had much time to drive it. I've put probably two hundred miles on the car with the parts. The part I like the most is that it is easier to get the rear tires to break loose. I can't wait for an intake and a tune for this thing. I think it just might hold me off till cams and valve springs are available.

Fantastic! So it does "pull" harder then...that is good to hear. Thanks for the input.
