Exactly. I have no idea of what was on the car except for the exhaust cause of the welds. Everything else looks peachy. Oh, and I do work in a shop 
I was just assuming that the car was stock cause of the low mileage. That's my fault for being lazy lol. I also gave it a quick rev and it wouldn't go past 6500 so the stock rev limiter is still there.

these are my lucas #42's. and zzp 2.9.
what size is your pulley? that would help us figure out what size your injectors are.
Well the injectors seem to be stock. I searched siemens 12790827 on google and they are stock. I'm not sure where to measure the pulley from (inside ribs or outside diameter). So the outside is about 3 1/8" (~3.12"). So with the belt being about 1/4" thick and sticking out of the pulley 1/8". Multiply the 1/4" by 2 (both sides), and the 1/8" by 2 and subtract the 2 of them and you get 1/4". Then assuming that the belt and pulley grooves are the same depth (1/4" divided by 2) you get 1/8". So take that 3 1/8" pulley and minis the 1/8" from all that other crap and you come up with 3". Sounds right to me I did all this with a stupid tape measure as best as I could and estimated the belt/pulley grooves. My digital caliper is at work (auto tech). So with a 3" pulley and EVERYTHING else stock, is it safe to run on 93? I haven't been beating on it because the darn dealer filled it with 87

I haven't been beating on it because the darn dealer filled it with 87 max boost will still be 12 psi, however you will get to max boost earlier in the rpm range. also the stock pcm will bleed off the extra boost that the smaller pulley will create. keeping everything safe.
there was a well done write up about this, by DENNY(one of our moderators)
i believe SS S/c: Got boost part 1 or part 2 was the name of the thread. do a search

I still have the factory warrenty. Think if I bring the car in and tell them about the pulley they'll voide the warrenty? I also don't need the car any faster, that's why I don't want injectors. I've had plenty of fast cars in the past (2 turbo buicks, supercharged/heads/cam lt1, 2 other lt1's, and crap like that lol), I just wanted a peppy 4 cylinder daily driver.

The dealer got back to me and decided to keep the warranty w/that pulley on I still want to swap it out or do a MBC on it though. From what I recall aren't you guys changing another pulley when going with a 2.8" and smaller supercharger pulley? Was it the tensioner pulley? My eyes are killing me (welding today) and I don't feel like searching and staring at the computer screen all day. Thanks.
Ok well I did some searching anyway and it seems to be the tensioner pulley being changed. I got some conflicting opinions though on what the stock size is. Is it 2.5" or 3"? Intense says 2.5" and South florida says 3". Who's right?

Well I just got my 05 ss and noticed that the pulley is a modular type. Just wondering if the stage 2 kit uses one like that. The part # on the pulley is TR2002. The injectors are green tops. Would the PCM have something on it too stating what was done to it? Just trying to identify what's been done. TIA
