Hi all, I think I have my winter project laid out and would love some feed back. Below is my list of intended mods and hopefully 650 crank hp.
- softronic , awe, apr tune ?
- Sachs 2.5 clutch upgrade - have already
- gen 2 intercoolers
- headers
- plenum 73mm?
- y pipe
- cargraphic loud - have already

From what I've read it seems like I can't go wrong with any of the above tunes for stock vtg's and I plan on Ipd for the plenum just not sure about proper sizing. I'm trying to avoid buying a package from 1 tuner as half the fun is sourcing components that will work and scoring a deal at that the same time. Thanks for any feedback.
