Would the Accessport VF34 map be good enough for these mods? I will be using the stock air box too.

- Perrin Turbo Inlet Hose Kit
- Perrin Intake Charge (MAF) Pipe w/ stock air box
- Perrin Performance lightened crank pulley
- Helix Uppipe
- Invidia downpipe w/ Blitz Nur Spec catback
- IHI VF34
- Walbro 255lph Fuel pump
- STI "Pink" 565cc Injectors
- Perrin Performance top mount intercooler w/ stock bov
- Perrin Radiator Silicon Hose Kit

 

With those mods you would be better off with a custom tune (cobb or ecutek). More effecient and more power

 

I'd definitely go with a custome tune over an off-the-shelf "stage map"

 

I dont know anything about ecutek? A local shop near me can tune utec too so I am just really unsure what to go with. What kind of hp range am I looking at with those mods anyway? Right now the only things I have is the Invidia Downpipe, Blitz Nur Spec and gutted uppipe. I have alot of parts to buy and work to do after the new year begins!

 

Find a shop that has the ProTuner software. That way you can keep your Accessport and have a custom tune loaded onto it while still having the benefit of other maps like valet.

 

STL WRX where do you live? Well if you live in the Bay area FLI just opened up a new shop with an all-wheel drive dyno allowing to get a custom tune instead of a generic over the counter map. AccessPort all the way!

 

I live in Southwestern Virginia... 3 hours west of Roanoke.

 

As long as you don't change the intercooler you should be able to run the stage 2.5 map from Cobb.Emailing Cobb with your question never hurts either or checking their forums.I think because the Perrin is a bar&plate design it has less pressure drop=overboosting.The wastegate solenoid duty cycle has to be adjusted.

 

As others in here have mentioned, get a custom tune to fully utilize the parts to get you the most gains possible with safety in mind. I would get an AP and have a custom map by having it Protuned.
