I know the lgo is a rougher engine than the ld9 as far as vibrations go, and i also thought the majority of vibs were smoothed out by adding balance shafts when the ld9 was produced. Well i have the ho exhaust cam with secret intake cam and i have noticed a major difference in vibration. Is this normal?

hmmm well... obviously a tune is going to smoothen the idle out some but are you talking in terms of like a lopey idle vibration difference or just a sheer, all out, all the time vibration like the difference between stock and aftermarket engine mounts do?

i mean some should be expected but i wouldnt think a major difference should be noticed...



180hp in 1989 or 145hp in 2002, you decide. >

Not crazy vibz like the whole car is vabration but noticed it is more than before the install. Broke o e of the exhaust hangers off the pipe. It was already starting to come off but its all the way off now.
