Thanks mate. Update time:
 
I replaced the seats and door cards recently so it's looking pretty snazy - but you have all seem Mr2 interiors before so I won't bother with photos. Been running strong the last few months. I have kept the boost at 12.5psi as I drive very slow vehicles for work so she still feels fast. Dynoed it this morning to check A/F and turns out  to be pretty neat. The power/torque curve below is not so neat lol.
 

 

 
What do you guys think? The red run was an initial run and the blue run he said was heatsoaked - but it seems like it takes a big dive after 164kph unlike the initial run. The boost reaches 12.5psi (it wants to go much higher) at about 130kph and stays till redline what do yo reakon causes the massive dive in torque/power?
 
This was mostly to check the A/F so I'm not too worried either way :).
 
Cheers

Boost is steady, as is your AFR, so for torque to drop off like that means its just not breathing properly after that point. Assuming there's no major restrictions in your intake or exhaust you're probably limited in the head, primarily cams.
Also is your igntion timing decent?

Thats a decent figure for a stock ecu. I'm not sure why your torque is droping off. Are you still running stock cooler.heat soak is a major issue for these cars with sidemount coolers on a dyno.id get a fan or something on it quick smart before you have issues with heatsoak like I did when I dynoed my car.
What exhaust is on the car?

Also on the afr chart why is the afr leaning out towards the end on boost

Thanks for the replies. My timing is not advanced and definitely still stock. Could be an area to look at however only so much room with stock ecu :(.
 
Hey Dom mate, I am working in Emerald these days (leave for my next rotation at 4am lol) so I won't make it this year. I'll see if I can't grab some photos next time I'm back  :). I am hoping to go on a similar run with a few friends with Nissans later on in December. 
 
Ebay cooler however dyno guys didn't have a fan on intake or on intercooler which would contribute. I believe the rev limiter caused the bogus  reading at the end. It has a random Blitz exhaust  I got for free - it has highflow cat and a silencer thingy that the exhaust shop recommended.

for comparison here's my dyno when i had it fitted. stock ecu etc. greddy cooler running 14psi i think. had an old blitz sytsem too but the exhaust was shot and restrictive.
 
i switched to gen2 NA cams, they have longer duration, slightly more lift but more imp better timing, allows engine to breathe much better up top. no noticeable draw backs in low rpm. also a single exit 3in system. loud and made a big difference. didnt get to dyno tho.:(

red run was just first at stck pressure, getting peak 10psi.
 
then blue green were 14 odd psi

Does your ebay cooler have a fan on it? If it doesn't thats the first thing I would fit. Secondly get rid if the silencer when you put it on the dyno.i will say again heat soak make your intake temps skyrocket and drop your power by a fair bit. Get a fan on the cooler if you dont have one it's s must on the dyno I found out the hard way.and dint run the fan off the engine lid temp sensor either set it up to run constantly.

Also, if your allowed near your car when its on the dyno, get a pressure weed sprayer from bunnings. Fill with distilled water, pressure it right up, then while its on the dyno have it spraying as fine a mist as it can in front of the vent(with your ic fan running constant)

Haha I was going to do exactly that but by the time I got around to it the car was slready tuned.it's a good idea thoughi was just going to use normal water.
