Noticed that my car was only running 8psi of boost after I installed the Apexi Power FC computer. Strange as I ran 14psi before with the stock ECU. I also noticed the exhaust temp guage light on all the time. I just assumed that the sensor was stuffed.

Anyhow, I pulled out the manual started reading and the red light means something is wrong. So with the hand controller unit I do a diagnositcs on the engine and it says that the boost is faulty..... WTF can this be??? :confused: Checked out the paramaters and bingo, the tuner set the computer to run boost from the Apexi Boost control kit which I DON"T HAVE!!! :( Last time I going there.

Anyhow, being a hot day today (summer in Aust at the moment) I decided to see if I was right and took the long way home. DAMN!! I'm running 255 wide tyres on all 4 corners and it's struggling to keep traction around corners. Distance between corners also seem smaller now :confused: :( Now she's running 14psi and the annoying light is off.

Just wanted to say that not all tuners know their sh*t.

LOL! :bahaha:

But seriously...it's a real issue knowing who to trust when you take your car to get work done. Do you ask a million questions and piss them off or just have faith??? :(

But, but... I like red. It's a pretty colour!!!:uh-huh:

Seriously, I figured the sensor was stuffed or cause my cat is gone anyway. When the dealer blew 2 pistons and a turbo, I don't think they checked the cat for the piston bits in there.

Silver,

the Boost control is set to 'on' when you plug the Power FC in, you have to manually change it to off if you don't have the kit.. Maybe your tuner didn't know this.

I have a new Power FC with Boost controller sitting in the drawer at home waiting to go into my new R33 GTR, just waiting on some cam gears.... Can't wait....

I got the car tuned at a big tuning place here in Sydney. I'd really would love to name it but for legal reasons I won't. I'm sure they've tuned heaps of GTR's with PowerFC's before. To me, them not knowing is unacceptable because when you go to big tuning shop, you'd expect them to know.

      What brakes on R34 GTT(Europe)

      Pads for R32 GTS-t, R32 GT-R non V-Spec (Sumitomo), R33 GTS-t and R34 GT-t are all interchangeable. R34 GT uses a 2x piston caliper, hence it didn't fit.

      Checked with amayama and nope, the full S2 manual set is not available anymore. Unsurprising, but still disappointing as the ? on availability gave a glimmer of hope.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
