==================

- There is also the separate subject of it being "deleted". It is also a top priority that you copy the ecm program out of the ecm and e-mail it to me for a proper review. MOST ALL of those "delete" programs are extremely harmful to the engine, will severely shorten the engine life, and this is nothing to play around with. I don't care how well you think it might have run before.

Copy the program out of the ecm and e-mail it to me for a proper review. i will tell you what someone did, good, bad, and downright ugly. .. and this is to ensure it is correct, safe for the engine, etc.

-- Does the engine still have its VG turbo?.
-- What hardware other mods might have been done to it as well?.

This stuff is no joke and means the difference in how long that engine lasts .. or eats its own guts out going down the roads... by as much as 75%.
