Taking the right path........
I have an 03 E55 Im just starting to mod Heres the list in order
Johnson CM30 or 90? Which one should I get?
Phenolic Spacer
LET H/E
ASP Pulley
Intake snorkel mod
Remove rear cats
Should I get a power chip or is the car rich enough from the factory to make up for the pulley?
I will infact need the power chip tuning after headers or an intake?

Your on the right path...the heat soak on this Beast is well known and anything you can do to decrease IAT's will give you more consistent power for longer.
The CM30 is the first choice just because of ease of fitment...the CM90 is more efficient but needs more labor to make it fit.
The more knowledgeable in the forum may correct me, but the pulley (ASP) or any other one won't be maximized without the ECU portion.
The next thing I would do is to;
1. Decrease unsprung weight (lighter rotors and lighter wheels)
2. Increase the weight differential to the rear (right now I think we are at 53%F to 47%R) to get more weight over the rear tires to increase traction
Good luck and keep asking questions...there are a lot more in the know than me by far and they won't steer you wrong.

Thanks very much...ps Im a huge fan of the look of your car. It inspired me to buy black hence my sig.
I also forgot to add the
Plug wires too...
I do plan to do the ecu but I do want to until I need to so It can be tuned all at once.
How hard was it to do your head lights. I think thats the first thing Im gonna do as soon as I get a chance.

They even look better now since I had the headlights and running lights done up with clear shield w/ 30% tint...I'll post pics after this weekend when after I get the car detailed w/ Zaino by my detailer.
PS...I had the the whole hood covered w/ venture shielding and the bumper, lights, spoiler lip, and the whole front fenders covered w/ clear shield. It looks great and the extra protection against bugs and rock chips is a must.

Really what do you suggest. I hear everyone getting the johnson pump. I was wondering about that when I looked it up I was why am I putting a boat pump on my mbz lol... what do you suggest? Also the asp pulley from what I gather is iffy about cooling because of higer boost levels but is a great match for a -10c/phenolic spacer/ heat exchanger/ pump...

Ok, check out this site:
http://www.daviescraig.com.au/main/display.asp?pid=27
Until recently, yes the johnsons have been the best option. BUT, now there is a pump specifically designed for our use that is copatible with the reagents we use for SC cooling, is more powerful, is brushless, is smaller, is everything but subjective.
My bosch OEM pump from my '06 E55 is as good as the CM30. How is that an "upgrade".
BTW, the Craig pump costs $200.

Do NOT put that ASP on the car without a tune, car will make less power as it will fight the additional boost with timing.
Jangy's pump is certainly worth a shot. We just don't know much about it as we are all programmed to think Johnson from years of use.
Otherwise you are totally on the right track. ASP will be fine with the right tune but you MUST have the heat exchanger and pump on first. Otherwise one hard run or two and she will go limp shortly after.
Snorkel mod just doesn't work IMO. Proven on the dyno by me. I literally took the tubes right off and had the car sucking air right into the airbox with a high flow fan blowing on them and no change. Just doesn't work.
Only thing you are missing are headers. Proven winner in perking up our cars. Let er breathe!!
Keep us posted.

The Davies Craig pump you reference is rated by them at 15 liter/min pumping against 10 kpa.
Johnson’s CM30P7-1 claimed flow is 26 liter/min with the same head pressure. Source, on page 18.
At least one member has successfully installed a Meziere pump...http://www.meziere.com/ps-892-860-wp136s.aspx

Sorry guys, i may have linked the wrong one. I'll be taking my bumper off and can write down the exact part number. I promise the pump is rated at 80l/min (almost 3X) capacity of the CM30 and it has much less restrictive fittings and many more advantages. It is an absolute no-brainer. I'm not hating, just showing another alternative.

or just upgrade too the last oem pump unit, which works fine. The cm30 was the buzz due to oem pump failing a lot. The last one they have works fine and is just as good as cm30 and is stock tested and no worries. Also covered under warranty if you can claim your old one is broke
new pump is on 06 cars

Yea but in order of priority for replacement reliability is number one but number two is more liters per minute for great cooling efficiency. So the new pump may flow a little more and be reliable but the flow efficiency of these other pumps is unmatched by the oem unit..

I agree that a CM30 is no better than the newer OEM bosch which (I can get for free. I wanted up in capacity.
