Last night my friend came over and we reverted back to the STi injectors and Link+ ECU. Ran outta time to get insurance, so today I called in 'sick' and we went for a tunning run, but only after figuring out a good combination of injector seals on the third try.
At first the Link was very finicky and frustrating. After a day of driving around, figuring it out, and charging the laptop back up 3 or 4 times, we have it tuned across the power band, up to 5 psi.
On an interesting side note, a factory, cat-less 2.5 RS cruises at an EGT of 1300*F. We have the Link tuned slightly on the rich side so it'd idle, and now it cruises at 1150 - 1200*F, even under boost. Almost can't get it past 1200* anymore.
It's a bit older, but for the price it's a nice setup for the time being, but we've agreed that when I build up my $1 engine down the road, that I'll get something more refined.
