APR ECU and APR HPFP

[Pappon]

Hey guys just bought a 2006 golf gti and was interested in doing the following things:

APR ECU
APR HPFP

Apparently from this i get the power will go up from stock 147kw 280nm to 188kw and 411nm. The APR HPFP from what i'm told gives approx 20kw at 3000rpm-5000rpm which i think is quite good.

Has anybody fitted the HPFP and what are the results and opinions? ALso do i need a diverter valve if fitting an APR ECU?

Also i know fitting an ECU doesn't alter insurance much how about when fitting the fuel pump? Any advice on this subject guys?

Sorry another question do most guys who fit the ecu upgrade brakes and or suspension?

Thanks in advance guys.

I suggest just going for the APR ECU as their fuel pump will not add power to your car. The fuel pump may come in handy for Stage 3 setups but you can always get that further down the track.

As you can understand, having the capacity for more fuel delivery is great, but if the stock K03 turbo is unable to generate enough air/boost to require this extra fuel then it is pointless; ie. the fuel pump itself does not magically add 20kW.

I emailed APR and i was told this

"With the fuel pump gains you cannot just add 20kw and 20nm on to the peak power. This gives a gain between 3000rpm and 5000rpm."

So i assumed that gave gains of upto 20kw at 3k-5kprm.

Okay so do i need a diverter valve DNA?

The first part of their response is a definite fact; the second part, well, let's just say I'm not convinced and leave it at that. A 2.0TFSI engine on stock turbo will not max out the standard fuel pump that easily.

I would recommend an upgraded diverter valve if your original one is beginning to show signs of wear, but again I'd suggest getting the tune alone first before then deciding what else you want/need. The standard DV, when working properly, can support faily high levels of power without leaking boost.

Cool, also i hear a constant argument about chips hear. What's the go with GIAC vs APR? Which gives more power and a better delivery of power? Or the benefit is so small we are trying to split hairs there?

[DNA Tuning]

Haha, I don't think I've been asked that question before... for obvious reasons, but um... here goes.

If you had to choose between GIAC and APR, I'd go the GIAC because I believe they are a little cheaper. If you want the switchability of programmes via the cruise control stalk then I'd go for APR. Having driven and ridden in several APR/GIAC cars, I'd say the GIAC tune feels abit stronger subjectively in the midrange despite not making a torque claim as high as the 411Nm that APR states.

If you want an incredible level of smoothness with the same peak power as the other 2, then go for a DNA tune. =)

lol John...

What power output do you offer DNA?

[DNA Tuning]

Our basic tune is rated at 184kW/380Nm, aggressive tune rated at 188kW/405Nm. $730 for either tune; 14 day unconditional money back satisfaction guarantee. Higher level/staged tunes available with accompanying modifications (downpipe, intercooler).

[Pappon]

can you switch the power like with APR?

Also you say smoother delivery than GIAC and APR? Is that salesmen talk, do you have a dyno graph to back it up?
