Ah thats a good idea posting those screen shots. Here's a couple....this is my buddies rom that apparently had my tune on it... Notice stock timing and fuel but modified mivec. Also notice the date on the one screenshot....we made this in November and its never been touched since then.

. This is dbsears statement which I was referring to
Well yea...Buschurs is about the loudest you can buy. I'm just saying there is no power benefit for 3.5in exhaust. You actually lose torque and off boost response. Same thing with cutouts. All find and dandy when you have a GT35 or larger strapped up with 30+ lbs of boost but on stock turbo that barely flows 40lbs

Apparently you have some data showing the loss in torque and off boost response? Just wondering...

We can rat hole on this, but the law of diminishing returns will agree that unless the car is already on the edge (i.e has every single bolt on in the world, cams, NOS, Vin Diesel and Paul Walker with the stock turbo) a switch from a 3" to 3.5" is going to be a marginal change at best. The 3" has already increased the exhaust flow for the stock turbo that switching to a 3.5" is most likely not going to change the flow enough to agree with Mr Bell in this case (good book by the way xturdfergusonx).
Now switch to a bigger turbo that outflows that 3" and then you are in business. So if you are doing it for a bigger turbo down the line then that is fine, but thats a completely different argument than the one we are getting into here

The point I am trying to make is you cant just go around spouting off that this or that doesnt work, cause one person said one thing just cause your an engineer and its "common knowledge". Did you forget this is evom and most believe everything they hear and see? Thats all...
. Way too many technical posts in here backed with dyno sheets, logging and relatively reasonable testing methodoligies not to do your research before buying parts. There are no excuses with the VIIIs/IXs (Xs get a break since they are new)
