Injector response time should be figured out according to your injectors!
As far as tuning a o2 map, using a scan gauge or something monitor fuel trims is the easyest way to start off! but if you do not have one, very small changes should be made with 2-3 pulls per change. You should always adjust fuel and o2 not just one or the other!
start with 1 degree of timing per boost pulled, then once you have that done. tune your afr's and slowly introduce timng back in and tune fuel accordingly!

Rob has a different approch to those questions than what i normaly do. The way i approch it is exactly how you explained but Rob's way is kinda neat and i was trying to get him to tell us how he goes about it.

You had me scarred for a min lol!!!
I street tuned a local here with the p-tuning kit last night..
12 psi.. base map needed some smoothing as afrs were jumpy and a little to much timing pulled.. 8 degrees for 10 psi....
Some tweaking and smoothing.. He was very happy! Im very happy with that kit myself.. and he will be the next one very soon to be in the 12's stock motor

It will depend HEAVILY on the individual's setup. For example, octane gas, efficiency of the intercooler, turbo efficiency, kit design etc....

How about map clamping? Tricks, hints, benefits? I'm trying to help the masses here since most of use boost junkies don't have the Mike special full EMS... bastard lol.

with ambiant temps reaching upwards to 105f on premium gas....imho not safe...that situation just makes me
...i could be wrong but better safe than sorry.

All depends on air intake temps along with the other factors. I have seen 110F intake temps going into the TB.

One thing you have to remember is someone's knock threshold will be VERY different from someone else's.
Example:
Someone running a 61mm turbo with an ebay intercooler running 5 PSI of boost on 93 octane will be different from someone whom is running a 50 trim on 8 PSI with a quality intercooler on 93 octane. Even if they are in the same area!

well when your dealing with ambiant air of over 100f you can bet on the intake air temps to be much higher. After all the engine is getting its air from under the hood and the pipes as well as the intercooler are just getting heatsoaked bad...for instance this guy had a scan guage which he was reaching close to 190f intake air....lucky for him the ecu was pulling enough timeing...but do you want to leave the timeing to the stock ecu when boosting?
