    Question, I have a UP and a DP I'd like to install in my 04 wrx pretty much everything I've read says it's ok on a '02-'03 becuase the tuning will handle it. I have a 04, and I'd like to install the pipes, I'll have the correct cable to do my own flashing with enginuity soon, and I'm getting familar with the software to tune it with, eventually I'd like to do all my tuning on my own car.

    What points would I have to change and monitor to make running the UP/DP combo safe on my stock car?

    I'm sure the OL/CL transition times need to be altered, anything else? I was thinking of maybe bumping up the boost fuelcut #, though I don't believe I'll actually spike any higher than the car does stock.

    I'm not expecting or trying to get all the HP now, I'd just like to get my stock up-pipe out of there and put the DP in while I'm doing that and have the car on a safe tune, safe tune being much more important than HP (anyday).

    I'd then be monitering my car with tari's datalogger to make sure everything looked OK, but any help on hints on things specfically for me to watch would be nice. Probabaly be watching 3 main things, AFR, IAM, and 02 (stock sensor)

    Stock 04 WRX, STI UP and Helix catted DP

    Any input? help? advice? Working map that I could either upload or atleast look at to help me?
