  1. Don't waste your money, not much you can do to the engine, other that supercharger upgrade about 10K, or buy a turbo 996 instead, other than that you are going to spend a ton of money for no more than 10 HP. Thanks for your reply and sharing your insights, Cesarfl. I'm not looking for maximum raw power here as I actually like the characteristics of the naturally aspirated engine for everyday driving. The upgrades I'm looking for make a noticeable difference at lower revs. If I end up with about 30 to 35 additional hp (incl. exhaust, air intake, plenum) and related torque gains, that's a 10 plus percent increase in total hp. I agree I seriously doubt you will get what these folks are advertising on a normally aspirated car. In some case folks lose midrange power and torque. I agree with Loren... I don't know about 35 hp.... change in powerband is more likely.... however.. I also have a 99 C2 with with PSE and found the GIAC ECU flash to be worthwhile upgrade... feels good after 4500 rpm and removes the lethartic spot in the 3.4 engine @ 3200 rpm.... I would recommend the GIAC flash and if that's not enough then some 200 cell hi-flow cats from Cargraphic (excellent quality) for more top end punch... the GIAC flash will adapt nicely to those cats... but that's it.. don't bother with headers.... I also don't know about the plenum... questionable. Thank you all for your feedback. Now, basically the consensus here is that the gains in hp and torque of any of the abovementioned modifications (exhaust, cold air intake, ecu upgrade) are, in fact, not additive? The manufacturers will state dynoed 10-20 hp at the rear wheels for any of the mods. To me it's then a question of making sure that the components work well together and lead to improvements in the desired segment of the powerband. For example, GIAC ECU flashs are available specifically for vehicles with performance exhausts and/or cold air intake fitted. Any downsided to the ECU flash as far as drivability is concerned. I would really like to keep the car as close to stock as possible with just a little extra low end power and proper Porsche sound (which I've already achieved).

  3. Greetings All, New to Renntech; love the site and am very impressed by all the expertise and helpful posts available. I'm sure this has been discussed elsewhere (but I don't seem to be able to locate the relevant post). I have a 1999 C2 (6sp) with a Fabspeed performance exhaust (from cat back) fitted. Sounds great and the quality is excellent. Any suggestions for additional (mild) performance upgrades? I'm thinking of helping the engine breath better and consider putting in a cold air intake and/or revised plenum. I've read about potential problems resulting from air flow sensors effects and check engine lights. Also, would you recommend starting to think about an ECU upgrade? Thank you.
