My baseline is really similar....I want to get tuned now!!!! haha

 

Hey Surf, was wondering if you had a lot of your mods on prior to the M370 manifold. I'd be interested in hearing what you thought about its' effect on your performance throughout the rpm range. BTW the underside of your car looks almost as clean and immaculate as Rochesters' motor bay,
nice work sir
Might also want to paint your Q300 cans black for the same look as soundmikes tail
Here's a simple DIY if you haven't seen it

1yr old car, and the OP lives in CA. But yeah, that underside is pristine.

Surfwagon, the O2 sensor wires... did you put those zip-tie loops in to hold them there, or is that how the wiring is normally configured?

 

I really like the look of the painted cans. I might do that. The M370 was the last mod I did prior to the tune. This was definitely one of the more noticeable mods I have done the the car. It definitely woke up the car. Sebastian says this is supposed to give more power through the mid range. I can't feel that precisely but it was definitely worth doing.

 

We don't really get weather in San Diego. We call it non-weather. I park in the garage at home and also at work. It stays pretty clean. The O2 sensors are zip tied.
