On my LS swaps I use as many stock LS parts as possible so if there is a failure you can get the part at the local parts store. The non-stock spare part I keep in my road side repair kit is the aftermarket fuel pump. I never had to use one! If the engine is stock a mail order tune should work fine. I used Frost Tunes on a stock LS1 and it worked great. Check over on LS1tech for other mail order tuners. If the engine has a cam or other mods a chassis dyno tune is the best. If you buying an engine that has a ton miles on it and are considering rebuilt fuel injectors make sure they come known rebuilder. It's critical to a good tune the injectors are flowing at what they are rated at like on a LS1 they are 28.8 pounds. Again check over on LS1tech.
