Hey, I've finally decided to get off my *** and improve my 2010 MRT. I had been running the stock map from the AP for about 2 years now.

That being said, I just purchased the Cobb SF intake and the TBE exhaust.

Question is: Do I need to replace any other parts to insure that I'm doing this right? I've heard that I should replace the Fuel Pump with a Walbro, and I need to replace a fuel relay. Not sure where to get that fuel relay or exactly what part to ask for.

Anything else to complete this setup at this level?

BTW, I'm in the central VA area if that matters.

Thanks in advance!

 

No fuel pump needed for the stock turbo.

Relay, yes. You don't want that going bad.

 

it would be safe to replace those things yes, but cobb does say the only things you need for stage two for sure is the intake and exhaust. again any more power and you should start running the pump and everything.

 

added the cobb stage 2, and am certainly loving the new found power. Still having the issue with the car nearly dying at idle with the AC on. I believe it's directly related to a quick change in air density when the AC fan turns on and blows hot air directly at the intake.

 

i just replaced my relay..it sounds like that could be the problem..its part number MR122409; 12 bucks at the dealership. quick change out under the hood in the fuse box

 

Yeah, I replaced my relays with the SSP 5 relay kit and still the problem shows up from time to time. AC isn't the issue either it seems. I turned it off and it still drops very low. At least it isn't actually stalling and cutting off.

Normal operating idle should be what? I'm at about 700 rpm right now.

 

Thats about right when the ac kicks on the idle increases
