Hopefully this is enough information. Does anyone have any stg2 maps for an 07 sti or should I use the stg2 map for the 06 wrx delta from turboxs as my starting point?

Mods will be:

APS 3" catless TBE
K&N drop in filter

Gauges I have:

EGT
Boost
Wideband O2

I am just looking for a decent starting point as I believe I have the tools necessary to tweak as I need to.

Is the '07 STi UTEC a Delta?

What about the STi Stage 2 from TurboXS's site? Link here (http://www.turboxs.com/stiupdate.htm).

It's Delta for 06+. Those maps are what I was originally planning to use then I saw that the version was different. I was thinking of using http://www.turboxs.com/deltawrx2006update.htm but it looks like both sets were posted same day. I will have to do a comparison of the maps I guess.

I tried the STI base maps on my 07 with the Delta. The fuel and timing seemed OK as a starting point, but watch out for the boost tables, with a catted downpipe it would go as high as 20-21 psi, but that's easy to deal with..

i guess a catless TBE would give more risk for overboost? I'll just lower the boost values in the table.

A catless would likely boost more. Start deliberately low in the tables keeping the curve shaped the same, then adjust to get back to the target values.

target boost should be 17-18 psi?

btw I couldn't see how the Delta would fit under the kick plate so I mounted under the passenger seat. If the cables for the remote switch was just a few inches longer, it would fit perfectly. As is, routing the cables took a little bit of time.

17-18 tapering to 13-14 should be about right.

It should have jump off bolts to move it up.
