The car is a 1993 R32 GTS-t, mods are:

S1 RB25DET swap

El cheapo T70 turbo @ 23 psi

El cheapo 38 mm gate

El cheapo high mount manifold

Bosch 044 in-tank job

3" straight through zorst

ARC front mount intercooler

Pod, BOV, etc

Stock internals, stock injectors, stock fuel pressure reg, stock ecu (tuned by Garage Saurus when in Japan, but).

The car made 196.7 rwkw @ 14 psi, back before we had the 3" on it (had stock exhaust with chopped/changed bits and big restrictive dents)

The 3" brings minimum boost up to 23 psi (tiny 38mm gate is fully opening, can't bypass enough exhaust, strange).

Fuel hasn't been an issue yet, the tuned ecu coupled with the RB20/25 airflow meter sees the airflow meter max out and the ecu starts dumping all the fuel it can, pretty much 100% injector duty cycle.

On the dyno run we were seeing 10:1 AFRs pretty much the minute manifold pressure went positive hey.

Now that we've got the 3", and the boost at 23 psi it's running well fast, seat of the pants dyno suggests around the 250 rwkw mark, with boost hitting HARD at about 4000 rpm, watering off toward the high revs (maybe down to about 20 - 21 psi). Blows away XR6 Turbos with ease.

Bit of fun! Microtech is next on the list, followed by RB20 fuel rail and some top feed 550cc injectors or something like that. Leaning up the mixture should help us make a fair bit more power, I'm hoping.

room for improvement at top end - nosing over a bit quick. Probably tied in with richness and getting to the end of flow capacity for this compressor.

mid range improvement likely to come with adjustable exhaust cam gear.

very driveable unit

    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
    • Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve. 
    • I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.
    • No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.
    • God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
