Default Where to start with map for the StreetTuner

I have finially made all of my purchases and am just waiting for all the parts to arrive. I am a little leary about how to approach the inital tuning of my car once the moddifications are done.

I am installing Helix 860s, Walbro 255, TXS FMIC and Shorty Intake, SMC Alky/INjection running 50/50, and a SBR 20g ported. Already have a Cobb catted DP and a Ti Cat back. Also have a Zeitronix ZT-2.

In the past when I did some of my own tuning it was using a UTEC on a Stage 4 WRX. There I had a stage 4 base map to start with so it made the first steps a little easier. Here I am not sure where to start, I.E. should I just start out with the Stage 2 map, the scale my injectors, do the MAF/Intake Calibration, then start looking and work in the order of boost, timing then fueling per WolfPlayers post?

I figure I will get the thing tunned at leat to the point were it is running well with out the Alky Injection, they turn it on and get the car more finied tuned after that.

Does this sound right?

Jesus... tuning that setup will be hard if you try to do it all at once. Best advice is to tune it for the Helix injectors and stock intake FIRST (to get the latency, TPS tip-in enrichment, and injector scaler value set right) and then tune it for the shorty intake (to get your intake calibration table set right) and then start tuning with a basic stage2 91octane map. Typically, boost is the hardest to get dialed in because it's such a dynamic thing whereas fuel and timing, you make a change, the car does it...

Cool that is what I am looking for. I don't mind doing it in stages especially if it makes it less of a head ache. Plus tossing everything on at once just makes issues harder to track down. I had been thinking of just doing the injectors first this past weekend after reading a bit.
