Hey Violacleff!
you and I are in similar situations with one distinct difference...your car is running!
What I plan on doing is setting up two different maps in the haltech with two different boost levels. the E6X can control boost with the addition of a 80$ boost control solenoid...heck of alot cheaper than the Eboost. check out page 59 of the E6X manual, its a basic explanation of dual maps, all you need to do is ground out the green "Aux.in" wire through a toggle switch.
although I would like to just take it somewhere to be tuned, im going to go ahead and purchase a laptop and WB setup so that I can really learn how to do this, plus when and if i make any changes to the engine I can tune it myself instead of having to schedule an appointment with someone. its a bit overwhelming to me seeing as how this will be my first standalone system and tuning experience but its not rocket-science...just time consuming.
you need to get a laptop and send me your map so i can start mine up
