not sure on gains tbh, quite a few peeps are going down the megasquirt route, still work in progress, a couple of people recently have upgraded the standard t/b for a mustang 57mm item and are reporting good things, jump on that site and have a look, theres loads in there for the 2k owner. wouldnt be without it. loads of group buys and stuff, theres not alot of intrest in the 2k really which is a shame so its nice there is a network of people who are constantly developing the car.
