In Topic: Adding more horsepower to my 2015 GT-R

23 August 2019 - 02:05 PM

E85 will give you more power, if you do not have access to E85, your next step would be turbo upgrades that will hold boost to redline unlike the stock turbos which taper way down to redline. Wastegates do not give much on stock turbos using pump gas.... all they do is add heat which increases the likelihood of knock...




Well im located in lebanon so we do not have E85 here
How much boost are you running ??
Im at 18 psi now

First of all you cant run the stock cal on those injectors.
Try the cobb ots map for 3" intakes and your injectors. If that fixes it, you have a tune issue.
Still didn't mention what fuel you're on.




98 octane l!!!
I tried the ots map also! Still does the same thing
