^ that's exactly what i was going to point out.

its the higher boost that is making more power, and all the E85 is doing is alowing more boost to be run without detonation.

I think my GTR could make near that if it were able to hold 25psi boost, but it seems to peak at 25 then trail off to 20psi

Anyway's, will see what it does on the dyno this weekend

Are you running standard or aftermarket actuator / wastegate springs? Judging by Donnans HPI article, youd see some good results with a stiffer spring!

I've got 14psi actuators from memory? i remember when i had them fitted to the std motor the tuner had to just run wastegate tension because when they were plumbed in boost would hit 18psi.

i've got an Turbosmart E-Boost Street, so it should be able to control boost well enough. might just need some fiddling with the settings to control the wastegates better?

shouldn't i just be able to have the wastegates tightened to hold more boost?

i think they're adjustable, they have a threaded rod which looks like you can tighten of loosen to adjust when the wastegate cracks open.

yeh go speak to jason at mtq.

my external gate hold 20psi flat, put 25psi through it and it bleeds back to 20psi, fitting a stiffer spring will mean boost holds and it bosst will come on earlier too :)

    • Yep, the closest base tune available was for the GTT, I went with that and made all the logical changes I could find to convert it to Naturally Aspirated. It will rev fine in Neutral to redline but it will be cutting nearly 50% fuel the whole way.  If I let it tune the fuel map to start with that much less fuel it wont run right and has a hard time applying corrections.  These 50% cuts are with a fuel map already about half of what the GTT tune had.  I was having a whole lot of bogging when applying any throttle but seem to have fixed that for no load situations with very aggressive transient throttle settings. I made the corrections to my injectors with data I found for them online, FBCJC100 flowing 306cc.  I'll have to look to see if I can find the Cam section. I have the Bosch 4.9 from Haltech. My manifold pressure when watching it live is always in -5.9 psi/inHg
    • Hi My Tokico BM50 Brake master cylinder has a leak from the hole between the two outlets (M10x1) for brake pipes, I have attached a photo. Can anyone tell me what that hole is and what has failed to allow brake fluid to escape from it, I have looked on line and asked questions on UK forums but can not find the answer, if anyone can enlighten me I would be most grateful.
    • It will be a software setting. I don't believe many on here ever used AEM. And they're now a discontinued product,that's really hard to find any easy answers on. If it were Link or Haltech, someone would be able to just send you a ECU file though.
    • Yes sir am asking is there possible way from aem tuner from wiring pins 
    • Have you checked cam to crank timing and confirmed balancer marks are correct?
