I do have the thread open for the 24x issues and I am receiving help. The thing is I'm not educated properly about how to tune and I do like to play with the small things. But when I have major issues with something such as tuning I prefer to have a professional handle it. Can anyone recommend a trusted competent tuner ( NOT PCMforless ) that is knowledgeable with LT1/24x setups? Either mail order tuner or local in the MD/DE area?
