Just so everyone understands . All my issues with BBT are workmanship related . I have a hood hitting the core support ,left front tire hitting the fender windows that don't go up and seal correctly, a ECM that will take a act of god to get out if it ever goes bad I wanted it relocated. That's the short list. I understand he just installs the parts he don't manufacture them I don't hold him responsible for any of that. My engine is a pile of SH!T ! It was his engine builder who built the engine . And I personally don't think he did anything wrong. From the time my car went to Columbus then to SEMA it was never tuned correctly . I hold him and the two ''TUNERS'' responsible for what happen to my engine . 44 DEGRESSS ADVANCE TIMING WTF COULD HAPPEN THERE ON A FRESCH ENGINE!!!!!!!!!!!!!! So that's where I'm coming from I don't expect a lifetime warranty with my car just fix the issues from day one.
