Sprint Booster

I received my Sprint Booster in the mail yesterday. Price $300.00

It took my 5 min to install. Remove two 13mm nuts holding down the gas pedal. Unclip the wire. Plug in the Spring Booster. Plug the wire back in. turn on power. Set unit to red for max power. Unplug signal wire. Bolt pedal back in. Drive.... Vroom....

I had a local shop "chip" my ecu... they actually had to pull the ECU.. drill a hole into it... retune it..and put it back in the car. Seems to work great! That and the muffler delete..well that didn't add more power... but it sounds great!

They made a nice difference in the handling department. Direct bolt on

2004 C320 4Matic
Upgrading to 2008 or 9 c350

Hey guys I'm about to buy a 2008 or 2009 c350. Which ever comes out cheaper, but since I live in New York I'm become so used to my w203 c320 4matic in the snow.

How is this with snow or rainy roads? Any feedback.

How do you like the muffler delete? Any drone? I dont know what to do to make it sound a bit louder while maintainin a deeper sound rather than a raspy sound. Some muffler guys suggested to slap on some Borla XS muffler since the delete causes drone?

Please let me know if I am mistaken or if that even matters.

Thanks
The W204's Post facelift have the M276 engine, not sure if it makes any difference with the RENNtech ECU upgrade though

Something to add for reference, here is a video of my C350 Coupe with an xpipe and Meisterschaft Exhaust since many users wants to hear and see what it is like.

I also a have CF trunk spoiler and CF roof spoiler on my car. If you want links and pics to those, let me know. They're from ebay though.
The exhaust sounds great! Also, who makes your diffuser? I am trying to find a decent one to fit my C350.

How did it hold up?
Any links?

Thanks
