IS38 - Heardtbreak on the dyno

[AZGTI2]

Is your car DSG? If so do you have the APR TCU tune?

Also what tune in the MK6 running? That will make a difference.

i am on a dsg with tune. k04 is giac with 6 speed manual. he was on water meth but running 91 tune. it was cold out so i doubt i was pulling timing. he dynod 305 on the above dyno on his 100 tune. hes also going back for the giac extreme tune, i dont think i stand a chance lol.

Sorry I edited my post above, MK6 GIAC K04 with meth is a beast, still you should pull a bit.

Check my theory about the DV, maybe there is a point where its weak.

Look into a Forge DV, I know that is what RJ is running and with one of the two springs they give you, you could be loosing boost with the Stock DV here.


I thought about this. Heard so much bad feedback about the gfb dv i never pursued it. Is there some way i can verify this through looking. im gaugeless atm, so in the dark on boost

 

[gn4rwhals]

Log boost pressure requested vs. actual in VAGCOM maybe, other than that I would look into the Forge DV rather than the GFB one.

I ran a GFB DV+ on my K04 MKV and it was fine, for some reason on the MK7 I got EPC lights.

The MK7 doesn't like the GFB DV+. No idea why but there's been a bunch of posts about it. Yeah OP do some logging and get back to us. It may be a low reading dyno but it cant be THAT low reading unless it is really in need of calibration.

Thanks guys. I will update with second dyno and try and get some logging done

How does the car feel compared to Apr stage 2? Was it a noticeable difference like stock to tuned or just slightly better like going from stage 1 to 2?

I skipped straight to the IS38. However, if you look at the second dyno, I pulled 240 with full bolt ons, stock turbo and tune. So now i am 43 whp higher with a larger turbo and tune. Car is quick, but it isn't where it should be, I am convinced of that

I'm guessing small boost leak somewhere, you can take it to a speed shop and someone should be able to help you out.

The whp gain isn't as important as dat powerband! That comparison dyno basically just sold me on this swap...

 

[gn4rwhals]

Powerband does look wide, but OP claims he is down on power a tad.

Jury is still out, I'm convinced people don't understand how fast GIAC K04 tunes are especially when swapped over to the extreme file. I wish I would of sent that route when I went K04 on my last car.

 

[Euro Tech]

Have you contacted APR? To be sure you got the right file?

Does the Golf R and the GTI have the same Dv?
If not maybe a Golf R dv could do the trick instead of buying expensive aftermarket parts.

Can't you log a run of say 60-100mph that run would say a bit about the powerband.

I've a JB1 seat Cupra dsg, basically a Gti with an R engine. I'm doing 60-100 in sub 5 seconds measured with racelogic / vbox No Bolt-ons.

According to Apr they recommend and use the stock dv even on stage 3.

When you buy the is38 it comes with the Golf R dv already.
