I'll buy your undertray when you buy one of those ed.

God dammit. Why must you post that? Now I have to spend money.

I don't like the hook tabs, but the rest is awesome.

It has a nice diverter built in on the top side which directs air up to the radiator rather than letting it pass from the bottom. Be careful if your I tercooler sits lower than the radiator and bottom of the stock air am trim piece. This piece is required as it uses the 4 bolts up front. My begi unit sits a tad bit low so it pulled the bumper downward slightly. Not a big deal when the sides are mounted but I have a lot of snapped m6x1.0 to drill out and retap for the passenger side to mount. The driver side I had to bend the rear most tab upward and will probably just use a self tapping screw or a rivnut

It's very cool, but I personally wouldn't buy it for my application. I had to cut my stock undertray a LOT for intercooler tubing and brake ducts. Not interested in repeating that process with aluminum.

Yea, totally understand. My stocker wouldn't work well with the intercooler and because so many snapped bolts reduced mounting possibilities, the stocker just wouldn't do for my application. Half the reason I rerouted the hot side was to simplify the holes cut into the tray and reduce the aggressive wiggles and pinching between the sway bar when it was routed from the front side (prohibiting the A/C compressor from mounting up)

Dropped the car off to get tuned. Hopefully it doesn't blow up in a week or find that it has shitty compression and leak down

I'm stoked!

Tuner just called in, did a leakdown and started tuning. In no particular order, using 100psi input, the leakdown reading/results are:

91 psi - 9%
92 psi - 8%
92 psi - 8%
93 psi - 7%

They said that there was some infrequent spark blowout at 22-24psi, so they had to gap the plugs to 0.028"

I'm getting giddy

:likecat:

It made 351WHP, working on getting the chart but I'm away on travel right now. Also I'm still on the stock (medium) IWG can. I'm reading the Full-Race EFR tech document, and it says not to pressurize this can over 19psi. Uh Oh.

:likecat:

How did you like PTuning's dyno? I have yet to get on it, but I was around when they will building their facility back in 08-10. One day I want to get up to get on it and try it out.

That's real stout.

Thing must rip like crazy

:likecat: hope you have an extra transmission handy

Their Dyno seems to be a "heartbreaker" but it doesn't matter as I have nothing to bench the gains against. I don't know if they've tuned any Miata's in stock trim. I think there was a dyno day recently, I'll have to poke around the local group.

As far as their service/review of PTuning:
From what I've read, they seem to be a bit pricey in terms of parts/labor custom jobs. Tuning seems on par with the NOVA area, but Ken knows WAYYYYYYYYYYYYYYY more than I ever could about megasquirt. I was just in for an alignment and he spent two hours going over my map and explaining what things meant, why you do this or that, how this could change. As though this is what he did because it was fun puzzle for him.

Every correspondence I've ever received from them was concise, and friendly. It made me comfortable enough to take my car there for a retune than other "Miata" shops in the area.

Like every shop, you hear stories. But not only did they ballast the driver side and dial in the alignment exact as I prescribed without any ± values, they went out of their way to help me locate and isolate other issues while the car was on the lift. My brake lines are apparently too short when steering lock to lock. I had an oil leak from the pressure sender. Little things, but nothing that they had to go out of their way for.

They walked me through the entire process of their tuning and setup of the vehicle down to the drivability and waiting for several cold mornings to dial in cold start and idle. To calibrating the knock sensor after tuning was done to ensure that the signal that was being read was noise vs knock. They called in to give me progress on benchmarks and made me aware of the timeline with each update and what they planned on doing.

As far as my transactions with them, I'm satisfied until proven otherwise.

I do as a matter of fact! Picked one up locally for $600


Now I'm just looking for another diff to install the 3.63 gears so I can reduce the mechanical advantage and truly shred gears.

:giggle:

Sounds like a legit place.
I really like places that go the extra mile like that, it's always worth every penny extra to go to someone like that.
