Hey guys I have been watching this site for some time and have not been active.

Here is the car I am building 2003 SL55 diamond silver, 24k miles, currently has upd 83mm clutched SC pulley, new Johnson pump, Eurocharged tune, belt wrap kit, k and n filters, secondary cats and resonator delete, 20" Rennen Forged wheels, lowering links, Carbon fiber interior, Alcantra steering wheel with metal paddle shifters. SL63 spoiler and clear side markers. Parts no installed yet: 82mm EC throttlebody and EC transmission tune.

Here is my build list, looking for guidance:
74mm fixed SC pulley- is this overkill vs 77mm clutched pulley
Heat exchanger
550 injectors
Trunk Tank
MBH Headers
New custom EC retune
Toe and Camber suspension kit
Open to maybe an AEM meth injection system to fight down AIT's
Maybe a FTP intake?

My goal is about 550 whp, 600 tq. Is this realistic is their a major part I am missing?

Any help would be much appreciated!!

We have his and hers at our house. Here is my wives 2006 CLS55. Programa lowering module with 19" concept one rims, and new grille. I am taking this over as my daily driver in 2016 so I will be building this as well. :-)
