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.

    • Before I commit to it as I already have the wastegate off the car, would you change it to the 9psi spring instead of the 12, or whack it back on now and try your suggestion?
    • Sounds good Hmm suppose the main thing is, how much do you care about this car? The filler doesn't make for a very good water barrier lol. If there was a tiny little bit of rust forming now, that in 3 to 5 years time becomes obvious under the paint (starts to bubble up), would it bother you? 
    • I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.
    • Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.
