New Turbo this weekend. Please Read.

[sickguy]

Hey guys, I finally going to put on a Big 16G Evo along with a ported o2 housing this weekend after owning my '97 GST for more than a year. I'll put on a 190 fuel pump and RC 550 injectors as well. My supporting mods already installed are:

Injen intake
HKS SSQV
Apex WS cat-back & RSR downpipe with HF cat
Pocketlogger
Apexi SAFC
Autometer boost gauge
Dejon Tool Dual boost controller

I have a couple quick questions any input would be great!
- I don't see boost creep on my T25 coupled with the 2.5" to 3" turboback which is a good thing. Can I assume it won't creep on the EVO turbo? as I think smaller turbos are more likely to creep with big exhaust. Please keep in mind my o2 housing is ported with divider cut out, but the Evo turbo is not ported at all. I just don't have the tools and knowledge to do some porting.
- What's the baseline settings I should make on my AFC after installing the turbo, 190 fuel pump and 550cc injectors? I just want to be able to drive home without running too rich or lean after finishing the install before starting to tune.
- How do I read timing on Pocketlogger? I pulled a couple runs and read some posts here but I'm not clear about ECU pulling timing when this is a knock. So do I add fuel to the RPM when that's a sudden drop of timing? What happens if it's rich, will the timing drop as well?

Sorry for the long post, but please give me some advice I really appreciate for those who help. I read here everyday but something I just need to be sure, better safe than sorry.

Thanks!

I have one more question about the boost level. What boost should I aim for with the above set up on CA 91 crappy gas? Anyone have experience with the similar set up and gas used?

Thanks.

RRE has an example of afc settings for almost your exact setup at the bottom of this page: http://www.roadraceengineering.com/newafcsetting.htm I have pretty much the same setup as you and these setting were almost perfect. Anyway, it is at least a good place to start.

Good luck man,
Kent

Thanks for the info. I'll try that setting after the install. Do I need to change the AFC settings if I run different boost? And anyone can help with the boost creep question and estimated boost level that can be run with my set up on 91 pump gas?
