I have tuned many cars with the haltech E6 system.
They are a good mid range efi system.\Make sure you run high impedance injectors and a good coil ignitor and you will be fine, if you have a big camshaft, I am not a fan of running closed loop, but that is up to you.Best to tune it with map for load vs rpm, not tps, as it makes a much nicer car to drive.and run the map sensor to it's own dedicated vacuum port.
