Time For A Tune

Hey guys! I've got a 33GTST running 7psi on low boost and 11 on high with the supporting mods:

3inch down pipe following to 3.5 cat back exhaust

100cell high flow cat

Front mount intercooler

Fuel reg

Walbro 255 fuel pump

High flow turbo

Spitfire coilpacks

Dual stage boost controller

Now that I've got these mods I'm wanting to get a tune and a new ECU. I need to know a good place based on the Gold Coast to get a tune and what ecu to get. I'm heading towards a Nistune. I've heard about EFI in southport and what a great job they do on Nistunes and probably going to go them at the end. My car has the factory ECU so wanting to upgrade ECU and tune before going towards more power gains. Will I also feel any difference with a tune? If anyone knows how much tunes and ECUs cost including installing would be great! Thanks in advance guys!

You will feel a difference when you wind your turbo up to 24psi or whatever it is suitable for. You will NEED a tune to make it work. Have you fitted all of the above? If you look closely you will find your car already has a fuel reg. Will your afm and injectors cope with your projected new power level? Don't forget to put spark plugs on your list.

Do some research to find out what you have to do to Nistune an R33.

Just to clarify. Nistune do not have a chip for the R33. You need to find the appropriate Z32 ecu or similar preferably one that can control the VCT. Simpler but more expensive is to get a Link which will do everything you need and more including obviating the need for a bigger AFM (you will need a MAP sensor instead - and an air temp sensor).

How much power is claimed for your turbo? Check that its maximum is not more than your injectors can handle - otherwise you will need a set of bigger injectors. And how good is your front mount?

Was about $600 first time and $200-300 for the second touch up tune on E85 compare that to a top place in brisbane ( not sure if i can name) who charged me $1000 just to tune a very mild setup with a high flow..

Having said that i try to give the tuner a good package to tune, so one with new parts/combination so he doesn't have to dick around with rubbish, but he will likely tell you in the before tune inspection...

      Wheel refurb?

      The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.

      Pops when backing off throttle, rough-ish sound through rev range.

      Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.

      It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....

      Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
