Hi,
Is it true that you can not run the 3inch vf engineering intake from a ko4 turbo unless you have a GIAC software, apparently according to my tuner they can not use the revo software with the intake.
Does anybody run a vf intake themselves on their own mk5 Gti?
-
total rubbish , i bet your dealer has his own he would like to sell to you !

Hi thanks for your help, That is exactly what i thought, but to be clear about the situation.... I the vf intake fitted a few days ago along with an Apr fuel pump, now obviously i haven't changed my current software from the mrc stage 2 map to cope with the additional items.
Since driving the car after fitting at a different tuner power seems to be 50% down. I phoned my original tuner an they explained that i need to refit my original simota intake as its the standard size not the 3 inch. Apparently my tuner spoke to the main guys in the meantime an said if i changed to there software don't run the vf intake.
Is somebody pulling the wool over my eyes somewhere along the line..
-
50% down on power . i reckon its something to do with the pump . was it a built pump or did you add the internals ? mrc are very good , why not take it back to them for a check over ?
-
iirc the maf cross section area is larger than standard on the vf intake.
Giac is apparently to only tuner to take this into account when producing their map.
-
why are you ditching the mrc map anyway ?
-
The pump is an Apr pump, the reason why i'm not going back to mrc is because the previous owner did the work on the car with the conversion an personally think a better job could of been done(aesthetically speaking), saying that the map they provided was very good. So I prefer to use the tuner that i have used for years saying that i used a different place to fit the Apr pump an intake as I was impatient an wanted it fitted the following day.
Should i remove the vf intake an refit my previous one as my garage reckon that could be what is retarding the performance until I actually adjust the software to the new pump.
