2001 porsche 986 boxster S w/manual transmission

Looking at Haltech tuners - was looking for a recommendation on which ECU would suit my needs?

* Primary purpose for my 986 is learning - DIY preferred and i look at working on the 986 as a hobby.
* Gauges and data that an aftermarket ECU can provide are very appealing
* I don't (yet) plan to track the car, it's a weekend fun car
* looking to maximize fuel efficiency and performance
* I live in CA so there are local restrictions that I should follow ;-)
* Have 74mm plenum upgrade and looking to add new air cleaner (987 or cold air induction) and a fabspeed exhaust

I considered the flash upgrades to the current porsche ECU - softronic etc. These seem safe but also "cookie cutter" and a "black box". Better than stock but I would like to be able to "look inside"/understand.

Recommend I stick with a flash tune? Or if going with a new ECU - what would you recommend? Anyone with motec/haltech/aem infinity experience?

Currently leaning towards a haltech so interested in Haltech recommendations.
