Need a bit of guidance - tweaking AP OTS maps for catless DP, other mods

[AutoEuphoria]

I don't have a setup that matches any of the OTS maps, so I am going to try to modify one of the 1.05 maps (stage2 + MSCAI 91 octane) to work with my setup (cold air intake, catless downpipe and midpipe, boost tubes, BPV, turbo inlet).

When first looking at what I might have to change, I noticed that my AFRs are a bit on the lean side (high 12s-low 13s) and I am overboosting a bit.

I've heard discussion of reducing the throttle - req load tables in the gears where I notice this happening, but are there any other areas that I will need to modify to get this to work well with my setup? I'm not looking for max power, but good solid AFRs (11s), little to no overboosting, and shooting for 17-18psi.

I'm new to tuning, but everything I've read makes it seem like I should at least give it a try before forking over $$$ to pay someone to do it for me. I hear the ATR software is easy to use, so I'm hoping that I can figure it out. I just want to make sure I modify everything I have to modify to get it to work right.

Thank you for any help!

I'm hoping some intelligible people on this subject will chime in because I would also like to know how to use ATR for when I get an AP. I don't ever want to fork over 300 or 400 bucks for a tune

first off calibrate your MAF and that should get your AFR's in a better spot again when you download ATR goto help and open the help file document and go through the steps of tunning pretty self explanitory

OK, sounds good. I'm in the process of doing my 50 miles right now. I installed the 1.05 map last night, and put in my download request as well. Haven't received the download link yet, but that's all I'm waiting for.
