I am ordering my turbos/inlets, etc... this week, but for now, I am either just puting on the turbos and running with my stage 1 program or I'll get a 5bar fpr and a stage 3- program from JHM. Now if I keep the stage 1 with the new turbos, I'm not expecting an increase, maybe more efficiant boost but if I go with the stage 3-, how much of a power increase will there be? Should I just wait on the stage3- until next year when I'd be going full stage 3? My wife and I are buying a house so most of our cash is going to that right now.

I'm doing the work myself and will be gutting the precats also.

 

Go stg. 3 - for now.
Stg. 1 tuning with k04s is lousy at best.
The only thing I picked up before I was Stg. 3- was more lag.

APRs B5 S4 support sucks so you can't get a custom ECU map.
Just the stg. 3 software.
I eventually plan on switching to GIAC because they seem to have better adaptability to different mods.
Where as APR there is hardly any R&D and you can't get anything custom.
