Evolve is suppose to nice. Lots of great reviews. AA just started making a handheld device so you don't need to ship out your ECU anymore. But a tune is pointless if you don't have other mods. The only main reason for it is if you have headers and need the SES light turned off.

The "best tune" depends on the region one lives, and the purpose one is using the car for. Here in SoCal, everyone must pass a tail pipe test at 15 and 25 mph on a rolling dyno, including a series of diagnostics when the smog device machine plugs into the OBD II port. More about this here in California, do any of the following and failing the bi-yearly smog test will occur:
1. No catalytic converters = FAIL
2. Turning off post cat O2 Sensers = FAIL
3. Agressive tunes contributing to adding hydrocarbons & Nox at low RPM = FAIL
4. Alpha N = FAIL
5. Visual "give a ways", i.e., intakes, SC's etc = FAIL

I have a stock air box with a MS filter, CSL headers, euro cats and I pass the tail pipe test using iridium plugs, as iridium plugs fire just a bit hotter to reduce the hydrocarbon content in the exhaust stream, and the software loaded into the ECU is ESS; I have passed the emissions test every time. My stock air box keeps suspicious minds at bay.

Now, for those living out of California where emissions testing is less stringent, using hot tunes like Evolve and Bimmerworld/EPIC tune may satisfy others. I have communicated to some on other Forums who have used ESS and then the Evolve tunes, and his comment was that there was not alot of feel between them, but if you're one of those guys that must have the best thing, it is my understanding that Evolve makes the best street tune, and EPIC makes the best track tune. About EPIC, that tune assumes the driver is very astute and monitors the gauges constantly because some safety measures relating to engine heat are turned off, so again, peform your research and choose carefully. Cheers all.
