Hey there I have an 03 CLS 6 Speed with AEM Intake and CT Headers but I'm looking for more power what should I do next besides going Forced Induction what are the best mods I can do to the car I have the TB but I haven’t been able to installed it yet. What do you guys think any help? please

 

Install that TB, I hear it really helps. Besides tint, that or the CT Ice Box will be my next mod.

 

he already has a intake. what about the cooling mods, or thermoblocks?

 

Pulley

 

UR pulley(s), OE Thermoblok spacers, Mugen cooling mods

 

Yeh....what he said

 

Save up for a blower, sucks to say but those other mods dont make a HUGE difference and the engine is already pretty tuned from the factory.

Or get some lighter wheels and focus on making it handle good, IMO 300hp is plenty for a heavy fwd semi-luxo car.

 

How much HP can the pulleys and cooling mods produce? I was thinking about and exhaust but considering the minimal gains of HP they're not worth the money that they cost. I would love to get a blower but I'm going to be relocated at work so I'm going to have to move so 4K is a lot spend right now but is definitely on my list. What about VTEC controllers? Do they produce any gains? Thanks for the info guys

 

The pulley and cooling mods will prob net you 10whp.

 

Won't the pulley alone give you like 8-9whp?
