do you have any type of piggy back computer or aftermarket computer. if not then you cant expect much. your afr's will be all over the place and (most probably rich) . once you get something like a SAFC2 (fuel only) or power fc (ignition and fuel)your power will go up to realistic levels.

Blaming the ecu is an easy thing to do. Could also be the dyno reading low. Post up a dyno sheet.

I wouldnt say anything is wrong.

Do the basics first, ie servicing(plugs/oil/timing/ecu reset, etc).

Mine pulled 175rwkw with only a catback and a pod and 12.5degrees and was only running 9psi.

thanks guys i changed the dump pipe and im installing an eboost with a fcd within the next 3 weeks just need money for the tune.

even with the dump pipe changed i have noticed a big increase in spool and top end pull, so looking forward to the e boost :kiss:

the cat is a xforce one so i think its decent

Please please do not install the FCD. Do your car a favour and at least try and get a Apexi SAFC II

I've got an SAFC II if you want one - sitting on bedroom shelf. I used it when I had similar mods to you - works well and gives other info like voltage levels, knock, etc.

Id be going a compression and leakdown test before anything else.

180rwkw is a base figure for thos mods.

Personally for mild mods like that i wouldnt bother with an aftermarket ecu. Your not really going to get much top end power. Fuel economy would be better though.

ive got 3inch turboback, profecb @ 11.5psi, fuelpump, fmic, pod, hiflowed injectors(unnecessary @ this stage), afc neo, made 197rwkw @ chasers then detuned to 193rwkw

tho it was just an afc it felt tad better to drive after tune

140 looks low friends auto made 150's with only pod and turboback @ stockboost

140 is way low..

mine made 186kw with dirty old apexi pod turboback and 11psi coutesy of a tap from bunnings...think it has a better fuel pump too..

whats your compression like....

you need to find the problem not buy more shit...you should be getting around 180kw...something is wrong..fix it then buy more shit...

+1

you have a problem some where and an Eboost will not fix the problem.

  • 2 weeks later...

is there a way to raise compression if its down or is the car f***ed . could this be fixed if the mechanic i am going to checks it out ???? i bought it stock and then i got a boost tee installed the mech installed it and dynoed it he charged me 550 and it didnt seem to go much better even though boost was increased by 4 pound . since then i have changed mechanics but havent dyno tuned it ... should i ???

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
