After countless attempts at getting my R33 S2 Gtst to make good power, I am finally there and happy.

It is making 360rwhp and drives like a dream. Prior to this it was making 305rwhp with similar mods. The real difference - the tune (tuner to be exact). Sometimes switching tuners makes all the difference....

Dont want to rain on your parade as this is a huge jump just on tune but was it done on the same dyno in same conditions as this might be a reason for some gain which is not really there?

I am sure that if the car drives in such a way that he has been excited by it, the numbers probably are reflected in driving experience :P

agreed there would be gains just not close to 20% gain... also worried about the placibo effect you know it must be quicker cause the dyno said so...

i am not trying to be rude i just prefer stats that are real in terms of this... example is my car is identical to my brothers as in we are 100% neck and neck every drag/race but he has 28hp more then me... this is not my skill but a different dyno different day.

some tuners are lazy, and just pull a big chuck off the stock timing and smooth out the A/F ratio, sometimes not even touching the Injection map, they just scale the Air Flow Meter which is purely lazy.

I've borrowed a datalogit and fixed parts of my map up, and added more timing after peak torque (using a combination of old dyno graphs).

yeah there is a certain tuner/workshop in Sydney who tunes just like this...it was a mates car so i re-tuned it properly and made heaps of gains in power and response as well as fuel economy...and i cannot tune for sh1t but know enough to get things looking reasonable. Made 450AWKW the next day at Autosalon and won him a trophy...yay :D

this workshop charges big $$ too...pretty piss poor.

      You'd want to cap off the re-entry back into the dump too. Just something flat that can be held on by the Vband.

      Thanks for the recap Matt Z. It was a great day out and I know you have said it already, but we couldn’t have done it without the volunteers.

      Looking at the photos, you could easily just drop this pipe and dump into atmosphere  Just 1 or 2 quick hits for data acquisition - if have a heat shield material and/or sheet metal, maybe just use wire/metal cable ties and attach it in a way to deflect heat from melting nearby wires.

      2025 PRP GTR Festival - A Massive Thank You from SAU NSW! On behalf of SAU NSW, I want to extend a huge thank you to our incredible committee for all the hard work and dedication behind the scenes. You are the engine that keeps this club running smoothly! (hopefully an RB lol😆) To all our amazing volunteers who helped make the GTR Festival Sydney such a success, thank you for giving your time, energy and sacrificing your weekend sleep-ins. Your efforts did not go unnoticed and were absolutely appreciated by everyone. We also want to give a big shoutout to the workshops, trade stalls, and the awesome VIP's we connected with over the weekend. Your support means the world to us, and we’re so proud to be part of such a passionate automotive scene. We are looking forward to collaborating with you at our future events.  SAU NSW had our marquee up for two full days at GTR Festival, packed with merchandise, a sizzling members BBQ, and a chance to chat with the committee, sign up, and check out some hot Skylines on display from our members. It was incredible seeing so many smiles and genuine conversations, that's what we're all about! SAU NSW is more than just a car club... we’re building a community where you can make friends, share stories, and talk about anything RB related or not. 📸 Please post any cool pics you took at the GTR Festival in this thread! 📸 To our current members, thank you for your ongoing loyalty, and to all our new members... welcome to the family! We’re beyond excited to have you on board! Please ensure you are involved as much as possible within the club, and make the most of our exciting upcoming events. Here’s to more future events, thrilling drives, chill meets and good feeds!
