L-jetronic is not 'tune-able' or 'chip-able'. It sounds like you have a pretty nice Spider there with a lot of reasonable up-grades/improvements already done. The only thing that hasn't been done that should be done is to post some photos here. We likes photos. They could even be of your Spider...

IMO, rather than spending a lot of money on engine upgrades you'd be better off spending it on tightening up the nut holding the steering wheel...!

I suggest you contact Greg Gordon at Hi Performance Store. He has supercharged the Alfa V6 & I4. He also is a dealer for SDS - Simple Digital Systems - an aftermarket FI management system.

Now then, no more replies until we sees some photos. If they gots a pretty female in the picture we might be inclined to offer you forgiveness. Otherwise we send Guido over to have a little 'talk' wid youse.
