Unfortunately wasn't logging Torque. Seat of the pants says whatever they did shifted the max HP range, and has given it an overall sportier feel. Adding the 74mm throttle body, tune, and opening up the intake restrictions definitely makes this car more fun to drive.
Thanks for chiming in...always a pleasure to talk with new folks. I've only been a member since I bought the Silver Streak last Monday and already have had some minor problems but gobs of helpful answers. This forum ROCKS! In so far as a tune, I really don't know if I want one yet. I don't race and I don't care about Ricky Racer in his turbocharged Honda beating me in the quarter mile. But a few more ponies under the bonnet for playful spirited driving is different. I'm going to be monitoring lots of different threads on modding the 3.2 NA. Not sure but from what I see, there are not many companies making parts for performance upgrades. These are the only people that I have found that offer kits for the 3.2 v6 in our cars, here's the link:
Kleemann - Tuning for the 32 AMG/320 (M112) V6 engines.
Thank you all very much for your help! Any additional info on mods for a few more ponies is highly welcome. I've owned and modded a 2000 Chevy Camaro Z28 LS1 and Ford Mustang 4.6 3V, so these little 3.2 German power plants are a new breed to me. But they all burn gas the same so there should be a way to get possibly another 40 to 50 HP out of these little beauties and still stay NA. So far so good I really like the motor...smooooooooooth!
