If u guys can tell me how i do know if the turbos are stock or upgraded. .

I bought a set of FVD 66mm turbos from someone and i tuned the car 2day my car has all bolts on (headers,exhaust, intake plunm, big throttle, IC , piping,Y pipe , meth all support mods . tuned by ESmotor , We tuned stock 14" GTR just tuned from master tuner Ben@GTC on 109oct , I race him from 70mph and he was keeping up with me till 150mph . the gtr is 100% stock just tune, so im disappointed i think the turbos i bough is stock

If you've got any logs of your tune post them up and share out a link to them. No need for excel or screenshots. There's a great website you can post a CSV of your log to and it'll graph them nicely as well. Check this out:

We use that quite often these days and it works great. The guy who implemented it is an avid BMW enthusiast came out of our awesome BMW N54 community, and the service is free and has been for a year or two now.

FWIW I think you should be able to take down that GTR even with your stock VTGs given your mods especially since the GT-R is on stock turbos and provided that you don't granny shift They need at least a stage 1 upgrade of some sort to put up a fight in a roll-on type race.

Thank you Dzenno

for the race between me and the GTR i just gave him 1 car and i was pulling a little up top . for shifting i was shifting extremely fast ( Driver Mod )

please check the logs and tell me ..

 

One thing I like to look at is knock sums across the entire motor (not logged above) and a reference to your ignition timing but overall the tune seems to be running healthy as your timing isn't changing much from gear to gear so I'll have to assume that is what is targeted in this case. Given your IATs are where they are across the pull and that you seem to be pushing ~17psi right now you definitely have some power left on the table with 93 octane (98 RON). If you're also running 109 (assuming VP's MS109 race gas?) then you've got quite a bit left in it from the power point of view.

 

Looks like this was logged with a durametric cable? They don't have the knock correction function defined for logging, Dzenan.

You shouldn't be unhappy based on your boost level. As he already stated, you are only running 17 psi which is easily supported by the stock turbos. You want to be up in the 22 psi range above 5k to actually get a decent benefit from your upgraded hardware.

 

Yes i was using durametric cable , are u sure a can go more than 17psi with non problem ?

 

The first thing I would do (If you have not done this) is go back to my tuner and ask him all these questions and let him review the files as he is the ultimate one who knows what is done to the car and he will be the one to solve your problem.

Emre is extremely knowledgeable with the 997 platform and i am 100% sure if your car is currently running 17 PSI it is for a valid reason, so ask him..

15-17 PSI can be achieved on a stock 997 turbo, so yes you can run over 17 PSI safely with a tune.

Just my opinion..

Goodluck.

 

thank u guys

 

A Durametric log will help.
Ultimately reading the file out is the best. We can even tell if it was flashed before.

Make sure you don't have any leak. This will effect the power massively. Also you may try to vbox the car. This will be good reference to know where you are in terms of power. As they stated good tune, fuel and your mods should be enough to take the GTR even with stock turbos. I doubt your issue is the turbos. Good luck

 

I got 3 maps in less than 24hr from Emre and the car is better now ..we are working on race gas map now .. i will keep u guys updated

 

Make sure you don't have any boost leaks. A proper test from the lower boost hoses will tell you. You have a lot of AM parts and with that sometimes drama comes when not installed and or matched right. Test it.
