car struggling for top end speed

[chriswilks]

car seems to be having difficulty pulling at the top end, been on vag com at the beggining of the month and all ok....had a couple of blasts and it seems to be getting slower
could it be the plugs??any suggestions?? running 210 bhp and 240lb yet 135 is hard work??

Probably just the usual stuff, boost hose leak, TB re set, ECU re set

 

[chriswilks]

cheers mate..ill have to try the tb reset.

dont think theres a leak as it hold boost ok.

how do you reset the ecu???what about if its been mapped???

Well spark plugs could be possible, after fitting denso i could easly hit 140 and keep going

yup 145(speedo speed) shouldn't even be a problem!

Disconnect battery, leave for 1/2 hour or so, the do same a TB reset
Not too sure about remap, but 99% sure that this will not clear it off of ECU
But only 99%

It cannot be wiped off as its overwritten the standard software. with out that the car wont run

hi guys,i think ive got the same problem,i have revo sps 3 and 130-140 isnt easy by any means,???????

 

[G2232]

are you guys still running of standard twin SMIC as this will pretty much be your prob if you are as you'll be getting heat soak

 

[chriswilks]

im gonna do the tb reset 2moro and if that doesnt work ill try new plugs!!although need time to test after that!

but if they dont work what then?????would a 4 bar fp reg make a difference?????

im running std intercooler might vent the arch too see if that helps.....although the car has done alot more than 135 even in the summer months???hmmm???

 

[Willie]

4 bar FPR shouldn't be needed, this is only needed at the remap stage
If it wasn't needed for the remap then if you fit it now you will have to get the car remapped again to take this into account.
Who is the car remapped through?
Has the car run well since this was done?
Did your remapper tell you to get anything specific fitted to your car before the remap?
Do you run higher octane fuel V power etc?
Do you have an induction kit or freer flowing standard induction?

Just push on the dash to make the car go faster, I do it in work cars and vans all the time. lol

Sounds a bit weird.

145 (clock) in a TDI "should" be no problems either, with about 500rpm left to the redline

Then again, my calculator could be wrong
