Invidia Down Pipe
 
So, I've been wanting to buy this but everyone have been telling me to get the Cobb Tuner or my engine will be running like shit. Any input?

Perhaps a little more time reading and learning about your car is in order...

For performance mods, you will need the COBB AP. This includes intakes and DP. It's more than running like sh@#. The stock ECU will make adjustments to timing and so forth that could lead to engine damage and/or failure under aggressive driving. At least that's how I've approached it as a first time LGT owner. Others can add their experience that have been moding Subies for a while longer

Summary - Balance performance mods with planned and simultaneous ECU map changes. The COBB website has a good list of do's and don't for mods.

Well, let's be clear. You don't *need* the Cobb AP. Most tuners can tune your car with open source software, but you will need to pay for the dyno tune. Unlike the Cobb AP. So, its pretty much a wash.

I thought open source was not available for the 5th gen LGT.

True, I used "need" in the context of flexability and convenience. Although not dugging into this too deep, I've never read of a single tuner advertising to bring any 5th gen, both NA and turbo in for a tune. Many 3.6Rs are itching to baseline and tune.

No open source deffs for 2010 (5th gen) yet. There is an open ticket at romraider requesting them. But there have been no new official deffs released since 2009.

For now, AP is the best choice. Yes, you should use one with a DP. Otherwise you risk blowing your motor rather quickly.

there are no open source options for the 5th gen as of yet, the guy who used to write the codes for our cars before now works for cobb, so you will need to get the AP to tune your car

That sucks. Cobb cornered the market on that by hiring the opensource guy.
