TREGTR

My post numbers are pretty low and I haven't quite figured out how to access this info. Are you able to help me out with where to find it? I recommended JEM, perhaps, in retrospect, I should have just put: JEM +1 without any reasons or ellaboration as to why I would recommend them to help you out. If you look back over other comments none have provided reasons, I did. I also did not say they were better, as I have no experience with DVS. The dyno figure seems high that "Envy" provided for -5s, coming from a qualified mechanic that has built a few. In fact, one of my builds is going to JEM next week that is extremely similar to what you have, hence the interest. Also, from past experience there is a lot more to a good tune than just an outright Kw figure. My intention was to draw the focus away from the outright figure, as this often leads to disappointment when there is no longevity factored into the tune for a street car where your expected outcome "is not 460kw but higher" on that set up. The intention was to assist - the responses make me wonder why I bothered in the first place. Welcome to SA for the new guy!

Same reason you asked

Interested to see a dyno sheet. No sender no oil pressure, usually follows no knock sensor

I have no affiliation with either? Once you go to both, you'll be able to tell us which is "best" in your opinion.

Have a look at JEM dyno diary page to see what they are making with similar setups for reference. It will be interesting to compare how the car feels after the tune with the figure that JEM gives.

Good choice. Technically not an argument when only one side logical though.

For what it's worth that figure with those turbos... the poor little things would have been choking for air. I had my R33 Gtr tuned there back in Brookvale days - boosted hard but the oil pressure light kept coming on and I had to back out. That was -5s 320kw. What boost did they get the 460kw figure at and was the knock sensor and oil pressure sender still attached?

Ummm... "unique" take on one part of what I said. I thought we were talking about the better tuner and the reasoning to this little portion of my entire comment is that they are passionate about Skylines. In fact, passionate enough to source a bona fide Z tune, which is "one of the most" serious skylines out there. My experience... passion drives performance. Put as a simple analogy, would you hire someone that turned up to a job interview in a flannelette shirt (Don't answer it's rhetorical)

on -5s?

Adam at JEM was confident enough to strap a white R33 with an RB26/30 combo on the dyno, SA night, and demonstrate infront of 30 or so SA members a high powered dyno run and then talk to punters about it casually afterwards too. Not to mention filming all their big dyno tunes and posting them online.

Any workshop that has a Z tune is serious about Skylines; publishes all their tuning figures online; holds Skyline's Australia nights and is willing to back themselves and tune a Lamborghini Gallardo custom twin turbo set up (pretty confident tuner). Very confident that Adam at JEM knows his stuff.
