Default MAPerformance Stage 1+ Package for 15-18 WRX Finally Here!


2015+ WRX Stage 1+ Package

MAPerformance is proud to announce the release of our Stage 1+ package for the 15+ WRX! As some of you may be aware, MAPerformance has been providing OTS tunes developed in house for a few of our popular platforms ranging from Stage 1 tunes for stock vehicles, to vehicles equipped with our hard parts. With that being said, I can’t ignore the most common question I get on a daily basis…. “What intake works with your Stage 1 tune?” To answer that, we need to look at how an aftermarket intake can affect the calibration of both the factory tune, or an aftermarket tune.

It should be no surprise to the Subaru community that installing an aftermarket intake on these cars isn’t always as easy as bolting one on, and enjoying the immediate power increase and drivability. Since the FA20 utilize a MAF sensor for load/airmass calculations, there are a few things that can affect how the car will respond with an aftermarket intake installed. From piping size (diameter and length), to MAF placement, can all have an affect on MAF readings. This is especially the case with our MAP intake, which utilizes a full 3” mandrel bent stainless pipe. With the larger pipe diameter and MAF housing, tuning will be required. Fortunately, MAPerformance has developed a tune specifically for the use of our intake system. The MAPerformance Stage 1+ tune will be free with the purchase of the Accessport and intake from us. Already purchased the Accessport from us? No problem. The tune will also be included with the purchase of the intake separately. Before we get to the dyno plots, let’s take a look at some of the features of the intake:
  • 304 Stainless steel mandrel bent pipe
  • Stainless steel heat shield
  • 6” Cone filter by Green Filters USA
  • 6” velocity stack
  • All installation hardware included
  • Fabricated here in Minnesota!
  • Free OTS Stage 1+ tune included (91 and 93 octane available)*


*MAP’s Stage 1+ tune is to be used with the MAP intake only, and cars using the factory downpipe.

Now let’s take a look at the results below:
Car in testing is a 2016 WRX using 93 octane fuel. No other modifications except the MAP intake and tune.


With the decrease of restriction or depression (pressure loss upstream of the compressor) compared to the stock intake (piping, air box, and air filter) we saw on average a decrease in wastegate duty cycle of 5-8%, showing the turbo was working more efficiently, and producing more boost and air mass more efficiently.

Feel free to email me or PM me with any questions at all!

Thanks for reading,
-Ian
