FI tuning question I am ordering HPTuners this week.
I am putting on my turbo kit end of the month.
I have been reading on how to tune and have an understanding of all that's involved...still learning.
Question for the FI guys, what is the first thing I need to work on to get into boost? I will be using SD.

the first thing to do is to license your car with the custom operating system. depending on how much boost your car will see, the are a few choices. pretty had to do a turbo set-up on a first tune. you and your motor will probably come out better hiring a pro to show you some tuning to get you going..

No, not for SD, you can't just pull a tune from a different setup and load it up. I mean you can, but it won't be right.
If you want that thing to hold up, there is no shortcut, you take all of the steps neccessary to tune your unique combination just like everyone else does.
Don't even bother beginning to tune (except for startup and idle) until you get your wideband.

I am going to place an order for one in a few days, just doing some research on the best one for me.
Thanks

1-bar or 2-bar SD?
The timing map is in airmass (g/cyl or g/sec I always forget which), not kpa, so keep that in mind. Thinking kpa when looking at the timing map will have you changing too little of the table.
The timing map is not extended going from 1-bar to 2-bar. So you have to build the timing at the end of the table, to cover the highest level of boost you plan to run.
2-bar will give you a Boost PE table to fatten it up even more, just under boost.
The VE table will make a quick up-turn where the boost comes on, then stablize again, because the efficiency of the engine changes significantly right there as the turbo gets spooled up.
Wideband definitely.
If you go to 2-bar, the VE table gets whacked (on purpose). Fix that up before trying to start the car. Copy in the old table into the matching regions. Make the boost region fat (i.e. 120%) and bring it back in line using the wideband.
