lol if there was thing i want to do to my supra is definatly rebuild the engine give that baby a new heart a modified heart that is

lol

LOL !!! advance/plus/low revs
retard/minus/higher revs

( i'm pretty sure )
it makes no difference what gear your in, the engine still behaves the same way.i don't know about you but when i give it shit the revs never drop below 3000 to 3500. HEY you only get lag once at worst, if you stay on the pedal a keep the snail winding there is no such thing .lol

There a lot more to it than just advancing and retarding to shift the output peaks... Cam tuning has little to do with the EMS employed, you'll get more out of it that way, but there's no problem with tuning your cam timing on the stock EMS.

Adjustable cam gears can get you a bit more power out of the stock cams, but they really shine when tuning a set of more aggressive cams.

i found a really good thread called 'cam tuning' i think , at 'celicasupra.com' . It was in the section for M series engines, IT might be in FAQ if it's not there, do a search, it was quite indepth. It should tell you all you want to know.

happy hunting!
