These are my actual results on 93 oct.
OEM- K&N filter
Stage 1- K&N filter
Stage 2- K&N filter, HPS intake tube and SPOWER catted downpipe
If you can read the dyno graph you will see that even though peak torque on the OEM tune was higher the Stage 1 still made more torque throughout the powerband and peak horsepower was greatly improved. With the addition of the down pipe in Stage 2 it allowed both horsepower and torque to increase significantly.
Sheddy does that mean that Stage 1 does not make as much torque or power in the lower rpms than stock?
No, this is just how the dyno was done, it was just the way the guy who ran the car applied the gas pedal. also those graphs are not 100% accurate the tq needs to be scaled differently because the graph is showing over 250wtq and the stats say 214, so one of them is off and the scale for the whp is off because this shows the stage 2 at almost 250whp and the stock over 200whp and 250wtq. This dyno graph needs its information fixed and cleared up.

Stage 2 requires an upgraded down-pipe.

I suppose I am somewhat concerned because, even looking at Sheddy's dyno chart, Stage 1 tune seems to make less torque than OEM at below 3300rpm...

My car peaked more torque with the stock tune at 3300rpm, but the Stage 1 overpowered after that. It definitely varies by the car, also when the car was dyno’d the WOT was done at different starting points.
can anyone in here answer me that how many water pumps are in our car ?
does the radiator water pump for engine coolant system sharing the workload with water-air intercooler radiator?

To my knowledge the intercooler has its own pump, meaning that we have two pumps but am not 100% sure

Sheddy, thanks for all the helpful replies. I'm sorry if I keep harping on the same issue but it is because I was just about to pull the trigger on a Stage 1+TCU with Tony to take advantage of the Black Friday sale and that I have to consider how Stage 1 is helpful for my driving conditions. You see, in Singapore, we are almost all city driving. There are short distances from traffic light to traffic light and moving off from stationary is one area where I experience the most frustrations with the IS200T. There is just this lack of urgency in wanting to build up power and get you going. If torque below 3300 rpm is lacking, then, in your opinion, does it make it even more sluggish in city driving conditions?
The other gripe I have with the car is the "lazy" way it shifts down and this is most apparent when I take a corner and then get on the gas. I am left with a significant interval before it decides to pick a lower gear and then build up power to push you on again. Again, I wonder if this is the engine, the tranny or some very conservative form of traction control at work... Does the Stage 1 tune with the TCU mod help in that sort of situation?
So there's less torque overall after the tune (looking at the graph)?
Agree that it remain a mistake between the graph and the text. In fact if your looking to the cross color you will note that Stage 1 for torque is green instead of yellow as for Power.
Confirm Stage1 give 36.899 Kgm and 206.08 PS at 4000Tmn.
I join an other graph wich is more significatif except that results (cross) are not at the same rpm for torque and power.
Must point out that TCU tune help in the gear choice particularly whether you are in Sport position and is much better in manual mode.
