well guys....found a cheaper alternative, 350 cheaper. I got it dyno'd before and after. completely stock at 144.5rwkw to 169.0rwkw. Very happy with the result, and now on my way to 200rwkw.

Im not an expert but i think it has to do with back pressure so i was told, from experience with my car i had a 3.5" exhaust with a 5" tip hks cannon, the car makes 330 rwkw and it did have lag. The turbo didnt cut in til 4000rpm.

Changed it to a 3" pipe and smaller cannon, it feels more responsive quieter and the turbo cuts in at 3500rpm.

wrong wrong wrong

Turbo cars = bigger exhaust the better

There was something else wrong with your setup, it wasnt exhaust related, unless said exhaust had poor bends etc.

Hence im going twin ~2.75" for my setup and only after 300-330rwkw

let's just say i removed the cat but still had the cannon out the back (making the car seem normal and safe) but in true fact had a GAP in the exhaust so all id have was an aftermarket dump/front pipe then an empty space then the rest of the exhaust.. would i have extreme spooling and extreme kw increase?.. (apart from the loud noise)

Do you mean putting a replacement pipe in where the cat was?

there will be a minor gain possibly

ok let me re-explain... complete exhaust system is taken off... all that is left is the dump pipe and front pipe safely bolted on the bottom of the car

The car will be so illegal it wouldnt be funny.

Your NOT allowed to run a car with an exhaust that finishes that soon, it has to be past the rear pillar or whatever to pass the most basic exhaust requirements

Plus it will be that loud you wont get far without half the neighbourhood reporting you.

So dont expect "extreme spool, power increase"... expect the "extreme ass kick" local authorities will give you for being stupid

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
