that's the exact set-up i'm getting in a few months. this might be helpful to me as well..
as for the accessport, just run weak and it should be more reliable. haha.

If you are using Cobb Tuning's off-the-shelf maps for the AccessPort, do not deviate from their mod requirements unless you have contacted them for information. Depending on the changes you make, your engine could either run lean in a certain RPM range or actually lose power. If you're lucky, Cobb may have a custom map tuned to your mods.
That's the only drawback to using off-the-shelf maps for the EcuTek or AccessECU/Port - deviating from the recommended mods can be a little risky. A custom dyno tune and reflash costs more but takes into account every mod on your car.
As far as the VF30 or VF34 as a daily driver, I know of people who use those turbos in their daily drivers and they say it is a completely streetable combination. These turbo setups are not considered 'big' turbo upgrades which is what makes them not seem laggy when properly tuned. One local gentleman even runs this turbo on his 4EAT and has had a custom dyno tune and EcuTek reflash and the car runs strong.

I've just put in a VF30 with the pinks and the uppipe, Got my accessport, slaped on the 93 octane map and I must say that it's a nice setup. If I would've gotten a VF34 I doubt I would even see any extra lag at all, That said, the VF30 is Very streetable. The VF30 does take a little longer to get going than the TD04, But it just KEEPS GOING!!!! I'd be really curious to see a DYNO of this setup. I've driven maybe a 1000 miles so far and it seems to get better everyday as the ECU keeps getting everything in sync. So I'd have to recomend it so far.....

why? The accessport is similar to a reflash.
the only reason I can really think of is that there isn't a tuning solution out yet for the AP's. So unless you're using something that cobb has mad a map for, you're out of luck.

Cobb stage 2.5 (TBE, VF34, STi injectors, fuel pump)...with an uppipe if you want, makes a safe, reliable daily driver. Stage 3 (which will probably be a stage 2.5 w/larger intercooler...probably top mount) should also be pretty daily-driver friendly. However, if ~330 crnk HP isn't enough and you start tweaking the maps/adding other mods to that you could be sacraficing reliability.

Lets not forget that cobb is working on a tuner as well......Also cobb does have the ability to make custom maps opon request. I'm just going with there upgrade path cause I can't afford to buy things any faster than that anyway, It's a win win for me.
