I think the only issue with the ASP is in the build quality. You get what you pay for. I don't know how much gains an ECU tune will add or if anyone has documented it. It would be interesting to see.

Many people are running the ASP pulley without a tune and some (including myself) have done a dyno afterward to make sure the A/F is still good. Our car comes extremely rich and even after the pulley, it's still very rich. If you search, you would be able to see my dyno.
The issue is that with the pulley just toss in, you will face the problem of cooling the compressed air, either the IC pump is insufficient or the stock IC is insufficient. The actual problem is that the ECU uses the IAT to shut off the SC and also uses it to reduce timing.

This isn't ASP but my friend had a Evosport pulley installed on his car (made a pretty significant gain). Then he got the PowerChip ECU upgrade and his car did run noticeably faster. It makes a difference. Its not needed but it will be faster.

afaik there is no inexpensive cooling mod - they're all around $3500...
but i hope im wrong - someone else chime in here....
edit: i suppose inexpensive is relative. im not sure i want to spent 3.5k on making something colder when i live in a city where the average temperature is 6.3oC (43F).

I think one of the thing that you may not like if you just put pulley w/o ECU is S/C jerk. It will be noticeably rougher than stock. Mine is Renntech pulley, which is a lot smaller than ASP. So w/ ASP, I expect it will be even rougher.
Some people like it, some people don't (including myself). The ECU, if tuned properly, will help reduce the jerk... I think by engaging the S/C in a lot lower RPM.
The jerk on mine was a lot less after ECU upgrade.... and hopefully will be gone entirely after my S/C clutch has been replaced
I'll give updates as soon as I pick my car up on Monday....

WaterWetter® is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30ºF. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass and bronze systems. Compatible with all antifreezes, including the latest long-life variations.

I used this in place of coolant in the Spec Miata mostly to avoid the glycol in a race car. For the E55, I think I would not bother with the Waterwetter though because I don't think it will make a measureable difference.

the best thing to keep IAC and engine temps the coldest is running 100% water but for most of us thats not possile due to climate. so water wetter is an additive that increases the surface area of the water/coolant contact (reducing bubbles when boiling), although i don't think the intercooler reaches temps that high its still helps, and helps alot more when added to the engine coolant.
the best thing is a larger double pass heat exchanger and a lot of people are saying the IC pump needs to be swapped out...

2 that I've done already are the -10* fan mod and getting a 160* thermostat installed. PTE, a forum member, makes the stats and you can get your stealer or a MB tech with STAR diagnostics to do the -10* fan mod for you. It'll probably cost you around $300 bucks for these two mods.
I'm also getting a new johnson cm30 pump($130.00 roughly) installed since my stock one is faulty. This should reduce the 'supercharger shut-off' somewhat. There are some threads flying around about some board members fabbing up an intercooler system for around $1500 also.
**edit: +1 on the water wetter too. Lots of forum members(including me) use this.

Yes,once the cooling circuit cools down and the IAT's come down,the SC will work again.Its controled by the IAT's and ECU.As the IAT's start climbing the ECU pulls timing and then at a certain point it kills the SC clutch.
