Yep. I thought buying new wheels would stop me from thinking about horsepower, but it didn't. It only delayed it.


Tonight I ordered the last parts I need to complete my fully bolted transformation:

ATP Downpipe


PTP Fuel Pump Internals




Now that I am committed, I am thinking that I will have to look into tuning my car with my AccessTunerRace (COBB Accessport) software, or paying ~$500 to get it pro tuned. I am leaning towards tuning it myself unless someone here knows of a good COBB tuning shop in CO. If you know of one please post! Also need a place to install since I don't have access to a lift.

Edit for misleading title lol

I've heard good things about Mac Autosport. Someone else with MS6 uses them. I haven't had a need to tune, so no personal experience.

LOL, finally gave in to the temptation huh Eric? lol

MAC pissed me off. They were tuning my car and dicked around with the throttle body settings after I spent 3 hours the night before adjusting it, and they messed up the tune so bad we had to tow start the car and then it kept dying on the drive back down here. It will be a cold day in hell before I ever let anyone at MAC touch my car again.

MAC did a good job with my tune on my MS3. Maybe they just suck at rotaries? hehe. Nah they get mixed reviews, a lot of times because Bill, the owner, can be a dick. But Nick, the tuner, is one of the nicest and coolest car guys you'll meet. If/when I finally get around to getting a supercharger for the Mustang, if I don't put it on myself, I will likely take it to MAC.

"MAC is whack"!

(too soon?)

Nice addition to the car Eric. Will make the wheels look better when you can lay more power down to them.

Shops tend to mistreat your car it seems

OP what are the specs on the DP dimension wise? And what bar are your FP internals rated up to?

Bill wasn't too bad actually, but it was tough to read him. Nick was the one that pissed me off the most. It's not that he was an ### or anything, just the fact that my tune was so jacked up by the time I left there and I still had to pay and barely be able to drive my car home, and that he messed up the settings on my TB. Dan was there during the tuning too, and they were pissing Dan off with all this though haha, he was surprised I kept my cool and he was about to lose his lol.

Indeed they do lol.

I remember that map from MAC, it was crazyyyyy. Sloppy timing progression and half-assed split timing, not to mention no water temp correction adjustments or even scaling the PIM values for higher boost! If I hadn't seen Nick's FD with my own eyes, I never would have believed he owned one, he tunes rotaries like a classic piston tuner tunes them- no idea what they're doing.

Congrats on the new parts. I've actually considered a DP as a final piece of plumbing on my ride, but I'm afraid A.) That any hopes of passing emissions testing will be long-gone, and B.) That I may create a "smoky turbo" problem, because of the inherent change in immediate backpressure.

For that matter, I'm a little freaked out that just my Test Pipe is going to fail me, come next emissions test time. We shall see!...

The only one i know of is here in the springs and its revolution motorsports, but i have heard alot of bad stuff about them. I would head over to MSF.org, and get one of the guys to do an E-tune for you.

Stealth1 on here has had his done like that, and that is the way i'm probably going to go once i get some extra $$.

all you need to do for them is do some 4th gear pulls and send them the AP logs. (i'm sure its more in-depth than that, but that is what i have found reading)

The temptation has always been there, but after years of driving the car with the same mods it just feels slow and has lost its fun.

That is a very worrying story about MAC.. I guess I better start studying up on what the safe calibrations I should aim for when tuning.

Copied from ATP: "Stainless, catless, high flow, Vband disconnect at turbo for modular use and future expansion. Comes with v-band module for stock turbo. Downpipe is fully compatible with ATP/Garrett ball bearing turbo upgrades. Direct bolt up to stock exhaust 2 bolt flange on the rear. Unit also has extra 02 bung for wideband tuning and plug included. All CNC machined flanges, 304 stainless tubing, and TIG welded construction."

I'm not sure what bar these FP internals are good for.

I know that my stock fuel pump only only flows 1600 psi max from old dataloggs... but this new one will flow 1800+ easily so I should never have a problem getting enough fuel to the camber.

You and I actually have nearly the exact same mods.
A ) I just passed emissions last month without taking any mod off the car.
B ) I have a couple of different smokey turbo solution's bookmarked on MSF that I will try if I run into problems... Still, I don't expect the turbo to live long while being fully bolted, which is part of the reason for me going with ATP so I can reuse some parts.

AFAIK there are no Cobb "approved" or "pro" tuners in Colorado for Mazdas, the closest we have here is Harvey, and he tends to really want to stick to the Subies and Nissans he knows.

Not commenting on any other tuners around here.

Keep in mind that while MAC may not be experts at rotaries, you don't drive a rotary lol. If I had an FD then I would be concerned about them tuning it, but they did a good job with my DISI and I was not the only MS3 to get tuned there. I don't know any other owners personally though to give more than just my own recommendation.

And yea I have heard mixed reviews about Revolutions down here in the Springs. A friend of a friend owns the place and seems like a cool enough guy and they've done a good job with my friend's 2011 STi so far but the DISI engine is a different animal than a Subie, which admittedly is MAC's wheelhouse as well. But I can at least say from first hand experience that Nick tuned my DISI and it came out great.

This is a good point and something to take into consideration. Just because they did a horrible job on my car doesn't mean they would on yours too, being a different type of engine and all.

However, I figured since Nick used to own an FD and says he knows what he's doing, that he ACTUALLY WOULD KNOW WHAT HE WAS DOING. Not on my car lol.
