the recent Eurocharged thread has really got me thinking ..

Things I would like to improve on my CLS55:

1. more responsive engine and transmission. There is a very slight lag when I want acceleration now. It's not something that bothers me much, it's more that I notice it when I stamp on the throttle .. there's a very brief "are you sure sort of glance" before it gets on with it.

I guess I want the engine to be a bit more ready to go, like my GT3 is. I know it's a lot to ask.

2. more power, say about 50hp. I really don't do VMAXs et al, so am not wanting loads more power. However, after 3 nearly years and 23k miles of 478hp, I very ocassionally think a bit more thrust and push in the back would be cool. I reckon that 530hp should be plenty.


Things that are important in respect of any mods:

A. I want mods that do not materially threaten or diminish the longevity or the reliability of the 55K engine and/or the transmission.

B. mods must be by well respected folks with top notch reputation, and widely and highly regarded by those with 55K engine mods.

C. not a fan of replacing OEM components unless new ones are proven to be better and just as durable.

D. cost is a consideration: I don't want to spend too much on a car that is not an appreciating classic. Having said that, I am happy to pay for quality and reliability.

Insurance wise, I don't want my mods to be so special and/or clever, so that it takes ages to explain the mods to my insurer -- I want as few insurers as possible to be put off insuring my car.

Thoughts and comments much appreciated.
 
A basic remap should get you the power you want. Obviously you can go the new pulley route if you want an extra 100bhp+.
 
The Eurocharged deal is an absolute stonker, and they have an exceptional reputation.

But if your car was mine then I would have some Renntech tweakery, link below:

Yours is an exceptional specification so I'd make some exceptional modifications. Many mods will make a car more difficult to sell, whereas Renntech will stand out from the crowd in a positive way.
