I called a shop here in Pittsburgh about getting a tune. He verified with SCT that they supported the LS (which I told him ahead of time) and that the device would cost me 389.00. Once the tune was installed he would have to dyno tune it but claims it wouldn't be worth the $$$ for only 14rwhp. He said the people at SCT are working on a new tuner for the LS and have a test model at their shop right now. He suggested I upgrade the intake, mufflers, and then purchase the tune and have the LS dyno'd; he also suggested I wait for the newly released one from SCT which will have pre-loaded tune programs?
