Hello guys I知 super new to the forum, and also new to the mb wolrd
i bought my 1st mb 2 months ago and I知 trying to gain more hp with a help of my close friend which he is a mechanic,
I bough the car with a 77mm fixed sc pulley 650cc injectors cat delete the car didn稚 have allot of power Idk what was wrong with it so I decided to make some changes on it, and this is what it has now

Longtube headers and straight exhaust pipe no cats
VRP V2 Heat exchanger
VRP 3 inch aluminum intake pipes
VRP Superflo cooling pump
70mm clutched SC Pulley
175mm crank pulley
Killer Chiller
650cc injectors
Dual 455 walbro fuel pump
One step colder plugs

I知 wondering how much hp can I gain with this setup and where can I have it tuned
