I am currently running Cobb stage 2 with SF intake, turboback, and boost pill removed. I am interested in decreasing the boost taper in the higher end RPM range and increasing the area under the torque curve (not necessarily increasing torque, just leveling out the curve). Wondering if adding a Forge WGA would accomplish this and/or if I would simply be over boosting at that point?

Did some searches on Cobb stage 2 and forge wga, didn't find anything that answered these questions... links to searches that do would be awesome, I definitely could see this being asked before just can't seem to find it

Cheers.

 

Yeah i am curious about this too. If you read the map notes from Cobb, it states that boot is set at 24psi and tapers down to 18psi. So i think this issue might be from the tune and not the stock wastegate; maybe to be safe???

I am debating if I should upgrade the stock wastegate also, but haven't found any replies from tuners.

 

from my experience, they dont make a OTS map for an upgraded wastegate. I have a tial 44mm but am running it without a spring at the moment because I'm waiting to get the rest of my parts for my tune. Im just stock with a turboback and intake with the tial wg. Having higher boost up top without it being tuned, my guess is it'll be lean.

 

Our actuator, from a mechanical standpoint, will have the EXACT affects on the boost/power curves that you're looking for.

I can't comment, however, on whether or not Cobb specifically offers a tune that will be able to keep up with the extra boost.

D-Sport magazine recently tested our actuator on their in-house Evo X and they picked up tons of power. 47 whp actually, at 6800 rpm. I'm not sure what tuning they were utilizing, but I'm trying to get my hands on their dyno graphs.

Here is a recent dyno of our actuator (with just a 10-15 PSI spring) on the VW and Audi 2.0T FSI applications.

42 whp and 47 wtq
