My engine does not smoke even at full pedal.

The facts:

Turbo diesel 5 cylinder 3.0L
15M Miles
Top speed 105MPH (reached by myself)
Acceleration from stop: medium
EGR & CCV disconnected
ALDA adjusted (like 2 turns ccw)

The engine performs decently. My question is: can I ambition more power from ALDA further adjustment or does the smokeless condition is a good sign of engine performance??

Smokeless is always good but little smoke should be there when the engine is cold and under hard acceleration or else it is a sign of lean mixture, the experts here would guide you better.

ALDA tweaked 2 turns CCW and NO smoke? Have you had someone drive behind you?
Where did you drive 105 MPH in D.R., There are some nice streches of road in your country, I like the trip from Santo Domingo to Casa DeCampo. I once had a cab driver doing 70-75MPH right through villages! A beautiful country you have!

Thx for replies.

My SUV definitely does not smoke. I have driven behind on my other car and also check my rearview at night when other cars are behind me.

I have a Rexton SUV which has a Mercedes Engine bulit by the koreans. I am wondering if my ALDA might be setted the other way because probably some pieces might differ in this design (Asia vs Europe). However I don't wnat to risk breaking the ALDA by turning CW - saw in other threads that it might break.

I have reached the top speed going east on the new DR expressways. Considering that the engine is pulling a 2 ton vehicle with a drag coeficient of 0.35, the power should be good to reach such speeds.

Let me know further comments

I didn't know Koreans worked in germany building engines....

I was watching a car show on TV about how China is becoming a big market for cars etc. They took the camra's to a car show and showed a little Korean truck with a diesel that looked like it had an exact copy of my 603 sitting in it!! Down to the lines on the valve cover! Mercedes must have sold the Koreans the rights to the 603! This was a 2004 or 05 model truck!

The code of the engine is OM662LA Turbo-intercooled

Going back to the question: is it wise to tamper with the ALDA on CW turns??

Do a search gsxr has some really good posts showing how to do this on the 603.
