Hey Everyone,
I have been enjoying my New to Me SLK320 with the usual updates: new stereo, sexy alarm, wheels, fixed top ...

But now wish to do some of these things to pep it up:

1) ECU tune (fav tuner?)
2) Pulley mod
3) Performance exhaust (tried MagnaFlow, no)
4) Plugs, wires ...
5) Airbox replace (e320 airbox)
6) Drilled brakes (low dust would be GREAT!)

What & in what order would you do ?

I am leaning on Tune & Eisenmann Exhaust but I would just like a bit more pep!!

Thanks!
Steve

wolf!

the pulley mod first. it will do more than the rest combined, i believe.
in all honesty, this is a peppy car , it is not a fast car. it will never be a fast car (without pouring crazy money into it, maybe)
If you want a fast car, it's better and, cheaper, and more reliable just to buy one.

With what you are thinking about you might get 10-20Hp. A good running stock 320 will do sub 7 seconds 0-60, 90's in 1/4 mile with a top end of 140+. How much faster do you want it? To get much faster it will be a 10K Kleemann kit (which makes no sense) or find a nice SLK32.

You state your car is a 320,, so what do you mean by a "pulley mod" ? From what I understand a pulley mod is only for a "supercharged engine" (SLK230 or SLK32). The 320 has no supercharger.
