MRT is a one-stop shop, but you pay for that with a higher price and being locked into EcuTek. It's your money in the end, and some times it's worth it because it's more convenient for some people. Pulse Tuning has my vote at the moment for a tune, and for mufflers get it custom made by places like Liverpool Exhaust who produced the Phat quads. They should be able to knock up a custom set for you for half the price MRT wants.
CV Performance used to be good, but ever since they started doing OpenECU tuning for the Libertys, they got really lazy. Some members (myself included) were in and out in less than hour (simply apply a map from a previously tuned Liberty and tweak). And the results tend to reflect that lack of attention too.
Tunehouse locks you in as well. And even though I've heard ok things from them as well, I haven't heard anything in relation to the Liberty. The tuner can be the best tuner in the world, but I'll still have my doubts if they've never tuned a Liberty before, or mistakenly think a Liberty will be the same as the Impreza.
