I just can't help myself. As I was told, "Old hot rodders don't die our pistons just seize up "!
You don't know anyone who needs these wheels cheap do you?

You guys can call me crazy, but I think the type of gas you get has A LOT to do with it. Not even so much the chain retailer (which does make a difference) but also between fillups at the same station. Sometimes I can go to one station and have my car pull VERY strong, almsot feeling like a 300+hp car in a c300 4matic (comparing to the g37 I used to have). Versus feeling like a complete snail from gas at the same station. Yes, I am taking into account differences in shifting, gear, etc. Under the same circumstances different fillups yield VERY different results.
Personally, I have found Sunoco to give me the most "consistent results". But I have gotten the best performance (even if only once) from Mobil or Shell 93 octane.

Yeah, that would be interesting to know. He could have pulled the mill and installed ah...........I have NO idea..lol .
I guess I'll just have to have her tuned and do the exhaust, the K&N's are already in. Talked with a tuner who said I should get great results since we run 93 octane here. Now what exhaust without being as load as the V8 was. You could hear me waaaaaaay before you saw me.

Yea especially when you get into the 3500+ RPMs its sounds like a monster...but hey it might as well sound like one because thats what she'll be eventually haha

@ergon: Being "over 60..." doesn't mean that we old guys have to slow down. Fortunately the C300 gets driven over 220 KPH here in Mexico every time it gets taken out.
But frankly, even MB feels that the C300 engine just isnt up to the job, and is being discontinued. The new C250 has MORE torque from a 1.8L turbo, nearly the same HP and turns out the same 7.1 sec 0-60. The C350 CGI gets another 38 HP and 20NM more torque. Both feature 15% gas savings.
That said, Matt at Powerchip stated in this W204 forum that the only real solution was forced induction. Some have quoted an investment as low as $4000, and improvements to 400 HP from the C350 engine. Realistically, 300 HP could be obtained from a properly forced induction equipped (turbo or supercharged) C300, putting it with the 335i in terms of power to weight ratio.
Unfortunately, all of the solutions mentioned in exhaust, intake filters and chip tuning, COMBINED, will only give about a 10% improvement (yeah, yeah, some will claim miracles, but this is the blatant truth). For all the time and expense, perhaps a forced induction system is the most economically viable choice with the best guaranteed results.

Have you modded your 350? I just got thru breakin w my new one and run almost dead even w 335i and kinda beat the xi with just the ECU tune and a full exhaust. If they are not stock forget it. Problem w those bimmers is they all look the same, I looked at one when my lease on the 08 was ending and I just couldnt feel it, even tho the mod capabilities are huge on them. If I did headers too Id be into the 300+ hpwise I bet

There are some turbo kits out there, the problem is first the install and THEN the changes in the ECU, mass flow sensors, cat sensors, dyno testing, etc. There are tuners out there that can get this done, as for the kits, here is one link:
http://www.mercedesbenzheadlights.co...o-kit-c-17_226
This still falls short of a 335i because of built-in limits in the W204: the 7G transmission is set up all wrong (except the C63 of course), the Agility Control and ESP constantly slowing you down as the yaw sensor would send out values far beyond your average C300 or C350 (again the C63 has different values and programming), the steering in the 3 is spot on, the W204 is numb.
However, the C300 costs $6,000 less than the C350, and a supercharger or turbo properly done would give you more HP, more torque and better handling due to 90 lbs less over the front axel. For a less or equal investment in the C300 vs a C350, the result would be a better handling more powerful car with improved gas mileage. Still not a 335i killer though, perhaps closer.

This little 6 just wasn't meant to be pounded on that much. A tune to get the most out of what you have - exhaust - K&N's that's about all you can do. This thing just wasn't built for pressure. Sure you can spend a ton getting it to go. But, it's kinda like strapping a 6-71 on a Pinto. You have to ask why.

I have it straight pipe with with the X pipe after the cats and a custom cold air intake but thats all as far as performance for now. Ive been wanting headers too and i will soon. I ment to put 335ci :/ haha Where did you have yours tuned? do you knoe exact gains?

I had OEtuning do mine. They will customize the tune for the octane u rum and any mods. I havent dyno'd yet just got it all back together. I did run it before and after the mods, I dropped a half second off 1/4 mile. With the exhaust mods u gotta be careful, some of the louder setups actually lose HP in stock ECU tune. Its very hard to do a proper cold air intake in these cars, 99% of guys that do it are sucking hot engine air in from the compartment and it sounds louder, but actually makes less HP if you dyno'd it. BCM filters will do more HP and breathing wise than an intake unless your pulling in air from the lower center grill

Yea imnot sure if ive lost any with the straight pipe but i did the corlaire intake myself an im pretty sure i set it up right. I work at an auto repair shop and we also do small performance stuff so even though im office manager I have the guys to help me out when i need it haha
