Need Some Opinions On 325is Mods

[Wonka]

Im kind of torn between gettin a Dinan or Turner Motorsport chip, w/ Dinan i've heard good things from everyone on their reliability, etc. but TMS claims 22 hp @ 6000 rpm vs Dinan's 18 hp. Also wonderin what a k & n short ram intake will do and if its the same as the Conforti cai?

first thing first, both those claims are very hard fought, ive yet too see anyone actually gain that much from a chip alone, you will gain some power but not like they say..... as for which to choose i personally would choose the TMS chip.

Yea I kinda figured that out I just wanted to get opinions from people who have either chip & what they think on it...anyone know about my intake question?

The short ram isn't as good of a design in my opinion. It works fine while moving, but while still it can still suck in hot air from the engine. Considering most people like to feel the power from a stand still, a true CAI would be a better way to go. Unless you feel like making a heat shield for the short ram style... Which outta the two, is what I would preffer, and do preffer. Less turns for the air to make coming in, perhaps a giving a higher velocity by not slowing down the air once it is in the intake... maybe it helps, maybe it doesn't.

I honestly don't see where the TMS, Dinan, or Active Autowereke software are gonna differ a whole lot. Keep in mind that regardless of whom you purchase software from, it's all doing the same thing (changes to the stoichiometric ratio, timing, etc.). I would be willing to bet, that they are all very similar chips, merely the cars they put them on may differ (condition of the engine, other mods on the car, quality of fuel run on that particular dyno day, etc. etc.).

I bought my software from Active Autowerke just because, they were the only autohaus willing to work with me, and build software beyond the standard off-the-shelf stuff. Dinan and TMS wouldn't. But I'm sure any one of the three off-the-shelf chips are terribly similar.

As for intakes, unless your looking at the full CAI (the down tube extends into the fender well) I would probably just replace with a drop-in K&N or Green filter. I just don't see the logic in the short ram intakes....the stock box isn't that bad of a design.
