AA or ACS performance chip

[Raiden]

Do any of you guys have any experience with either of these chips? I am leaning towards Active Autowerke because I hear it gives really smooth performance and is great, although I believe the ACS chip gives you more HP.

If any of you have experience with either of these, let me know how it is.

Thanks,

If you're in the US and drive an E46, I will go with the Jimmy Comforti Shark Injector. By far the best and value for money. AA is alright but their software is more tailored towards their mega turbo/supercharged cars. ACS chip? Didn't know one existed, unless it's a re-map. Either way ACS will be $$$. Alternatively, try Dinan. Although much hyped, their software seems to go quite well with their large bore throttle body conversion.

Perhaps its a fake then? I saw a few ACS chips on ebay, although perhaps they are just scamming people. I am planning to have this for an E36 325is, forgot to mention that, sorry. Also, yes, I am in the US. I'll keep what you said in mind. Any other opinions?

Thanks, :)
