Thanks for your input on tail pipe readings inaccuracy, I would assume so much with it being more open to the atmosphere than further up the exhaust line.
No wideband as of yet because others have been here before, its mostly charted territory. Would i assume my car behaves exactly as others? No. Am i confident enough to assume i can drive conservatively for the time being without major risk? Yes. Do I want to run MAPECU3 to correct inefficiencies? Yes. Would this entail installing a wideband? Yes. Maybe you and others dont agree with the order I am approaching this build, but give it time. My car is one of the most modified cars on the forum, i assure you i wont half-a** the build, and its my first boost project so I have a learning curve, admittedly, but i have talked to nearly all the past and current boosted 2IS'ers before attempting this to instill confidence in what I am doing before following through. I did not blindly go about this.

Not arguing yours and the others who are shocked i have no wideband, even i see it as driving blindly, but again, no one i have talked to has said anything wrong about my setup with my driving style. Thanks again for everyones comments. Still dying to dyno it but I think I'll wait until my gauges come in so i can log and see my actual AFR and boost under the heavy load of the quick dyno runs. But still, I will provide evidence of the gains i receive from boosting soon

Just curious, why did you choose SC over a nitrous? I was looking for more power last year and went to buy nitrous for drag racing. But ended up selling it since I wasn't planning to keep my car any longer. ISx50 can reliable use a 75 shot and a setup cost around $1500 for a fool proof system.
but parents wouldn't let me

Yourself and I may be approaching performance from two sides of the fence. I just wanted the show aspect of having a supercharger setup and the additional daily power, from your statement Id assume youre more interested in time slips from a track, but I may be wrong. Both good options though depending on what you want! A friend ran nitrous on his is250 for a while and loved it.

I just wanted to add -
^Back in May of this year I posted the following (seems like forever ago)^... I will conclude and say 7psi is safe for the few times you will hit and hold it street driving. Just watch on the dyno and be cautious at first because the stock ecu will have lean spots. Longer term you will be fine on 7psi. Save your $ for the meth/water.
I spiked 12.1, .2, .3, .4 a few times holding 7psi WOT and always let off the throttle because those numbers on just about any car seem like the line drawn in the sand. From my observations the car does like lean...but lean in my eyes is 12 a/f max. Anything over that knock seemed to follow and the stock ecu would completely freak and pull all power.
I've moved back to 5.5psi on the stock ecu and rarely do I see a 12 a/f...but I also dont get ridiculously rich 10s either. Its a happy median but some type of EM is in order to really get gains from whatever setup anyone is running on this car. Makes me want to try the map ecu but I just dont have the time to play much right now!

I dont plan on dyno-ing until i get my gauges on so i can record a more accurate peak AFR and monitor better, but that wont be long, theyll be here Friday. Just need to find someone to install the O2 sensor for the wideband, the rest i can knock out myself. The new DM-6 PLX gauge looks pretty cool, I'm a sucker for electronic gadgets so they sold me easily. I want to eventually get the Kiwi Wireless addition so i can view all vital signs on my iPhone/iPad, but then also hack my Nav + Phone so i can display my iPhone screen on the nav. That would be pretty sick
