hey guys i reccently had my rb25 tuned, the problem is the car only made 192rwkw on 12psi, even though when i load it up it stays at 10psi, ive seen many std rb25's make this with std ecu etc and now im questioning the tune,the car had some high knock readings under light throttle uphill say 3000rpm not giving it a hard time. to the point where they had to pull timming out from below std settings. this also didnt make much sense.. mods are:

rb25det

std turbo,injectors,afm

greedy plenum

front mount

3inch exhaust

600x300 cooler

fuel pump

powerfc

boost controller is profec B 2...

i wouldve assumed an easy 200rwkw should be in order, the motor is very healthy with good compresion and lil to no leak down...am i expecting to much from these mods? whats your thoughts?

yea thats what i was thinking, realistic dyno. only problem is it doesnt feel all that well on the street. unless i was just expecting to much,i just cant understand why they had to pull the timming out "less then std" in some load points around 3000rpm. it makes for a very "doughy" pick up if you catch my drift.

Ryan,

My RB25 was 195rwkw with same mods minus the plenum.

Maybe go to another dyno tuner for a comparison run?

Or, with my tuner, he says if Im not happy, bring it back and they'll fix it!

Give the person who tuned your car a call and have a chat and tell them your thoughts etc!

Cheers,

Chris

The only way your going to improve this figure is with an adj. exhaust cam pulley so you can get some timing into it [then you can pull it back/trim it to suit]. Then I'm only thinking around 200 -210, so you might make a slight diff, but if you have plans to go bigger turbo and cams etc I wouldn't waste my $$$ on a cam wheel.

    • Oh, I forgot too, all the multimedia stuff captured and sold through things like people playing Pokemon Go. Pokemon Go specifically, can actually be traced all the way back to a CIA investment company too. So yep, they're watching everything. Not to mention the new stuff where they've worked out how to use WiFi signals to be able to map occupants inside of a building. That one would be something that I see being more used in public/government buildings, as you need to understand the signals when the room has no one in it first. It's not as easy as Hollywood would like you to think it is.
    • Followed ☺️ Assuming those are NEO rods, then at least 400kW all day.
    • Lets keep this going , Spotted this very stock V35 in Penrith and also saw a nice R32 FLY past me on Castlereagh rd , sounded really good.
    • Great work! Give it a clean up with some Emery paper, and I'd run a thread die over the threads too to clean them up. It will make reinstall much easier, and also life easier for the next time it needs to come out.
    • I'm not a fan of high humidity, it's one reason I don't mind being further inland out Ipswich, except the last 3 odd years, the drought broke, and it won't stop raining, which is making the humidity nearly unbearable when the rains are in during summer! For me, my body hates the cold, once the cold sets into my body, I'm totally screwed. I end up with severe muscle spasm in my back/shoulder muscles, and it feels like someone is trying to tear the muscles out. I have no issues with it getting stupid hot, so long as the humidity goes away. So the last 3 years as above, have been woeful! Ha ha. However, June 1st, and I'm only just converting from shorts and a tee, to long pants and a t shirt. And that's mainly as it's a bit wet and miserable and I wanted to work on a car.
