ZEMDOG--i can't tell you which mod was the best, i did them all together as a package and my car returned a different animal.
1999Porsche911--no need to be condescending (loud=speed). i think it was due to a 'tired' SC'd 996 engine, hence, the explanation that it had 50k plus miles on it (and most were hard with SC). i would fully expect a different result from a 'properly running' car and i never 'claimed' anything different. However, there is not as big a difference between our cars as you think. Now the EVO GT700 that always passes me like i'm standing still is FAST. REALLY FAST.

If you don't want to be challenged, the don't make ridiculus claims. You stated: "BTW, my car as modded picked up more power than advertised. It can run down a stock 997C2S (355 hp) and a 996C2 Evo Supercharged/Fabspeed exhaust (400+hp---50k miles old)" Nothing about either car running bad. The SC'd car must have removed his sepentine belt for you to catch it.

As far as the mufflers, yes I totaly agree that its all sound and no added performance other than the 50lbs loss.

No mufflers = better low end torque and throttle response. Horsepower difference is only like 1 or 2hp. Torque overall is only lik 1 or 2. Better drivebility though without a doubt, as long as you r not scared of the sound lol

Throttle response is not performance IMO. 1-2hp is not performance IMO.
Adding 10+hp is adding performance but adding 150+hp is adding fun... lol.
The stat's I've seen from the sc kits are pretty poor. 70hp is really good but I'd expect more from an sc. Maybe I'm too used to LS1 engines where adding a 7 to 9psi ATI procharger gives you massive gains.

ANY gain is performance. If your a horsepower guy then you probally are one of those guys I would lap on the track. More torqe down low is not a gain?!?!? Isnt that the difference between the 2004 996 and the 2005 997. Welcome to Porsche my friend its not all about horsepower.

of course the ls1 kits will make more power. it's got 5.7 ****ing litres behind it 
. the porsche engines are 3.4-3.6 litres. stock the ls1 is making 345 HP, that's CRAP for 5.7L. the 3.4 makes 300HP and the 3.6L make 320HP.
when you look at the percentages the gains are close but the LS1 STILL need 5.7 fkucing litres.

i can believe your modded c4s can run down a 355HP 997 c2s but a 996 EVO SC? i had all the mods you now have and now going having the SC i can say NO CHANCE.

Im just looking for like 315 horsepower. I think the chip is the final fronteir. I just need to know what works?
? YES it will work on a '99. I had my car flashed and IT WORKED. i had the EVO/GIAC flash, EVO v-flow, headers, exhaust, lightweight flywheel and, FWIW, i got 280RWHP~330HP.

my friend with th 3.4 SCd was on the phone with EVO as soon as we got back from the track. They are guessing blow-by or a leak in boost pipes. he is bringing car in for SC system check and then compression check. but he has no CEL.
