    remaping a 2.5 tdi quattro

    Hi All,

    I have remapped almost allof my previus cars, vrs x 2, leon, gt tdi etc, but I have heard that my new car a 2.5 tdi does not perform well to a remap. Is this correct? Any opinions and pros cons of doing this to the 2.5?

    Most 2.5's will go to 200-210bhp with a normal remap or tuning box, above that and you start to need to look at new injectors etc apparently.

    I get 33mpg consistently from mine with a DPT tuning box giving a claimed 210bhp (I've never had that verified).

    My mate has an avant and has his rolling road mapped and has achieved 240bhp - witha power map.

    Just a remap? Not a chance, 210 at the very max

    Was it a standard car or had it been modded before hand. Interested to know about any other mods.

    sorry. with all respect, if its just a remap, its not 240.

    bhp is calculated by many different factors & rolling roads can be calibrated to show different readings. i'm sure if he went to a different RR centre, he'd see a different reading.

    Am I correct in saying that the bhp figure after a remap depends on the state and condition of the engine in the first place - a tired, worn, out of tune engine won't be 180 to start with - so the final figure won't be as high.

    yes, thats right mike. any decent tuner will check the condition of the engine & perform a fault check to insure the engine is running as it should before its mapped. thats why they normally offer a pre map rolling road to compare the actual difference.
