Hi, First post. Great site I might add!
I currently have a 240sx with an RB25/ turbonetics 62-1 T3 with a gt35r .82 housing@ ~14psi/ aem ems
Anyway, I recently dyno'd and looking at my graph I was wondering why I don't have a sizeable TQ drop these engines usually have at the top end. The green line is the first run and the red is the second where I added a little bit of timing to the top end. Boost was oscillating and that's why it's wavy.

Does it mean anything at all?
Turbine housing big enough?
Too little timing?
Any help is appreciated!
Thanks
Dynoed and no drop in Torque?

Re: Dynoed and no drop in Torque?
I would be happy when an engine achieves this kind of flat WTQ line. Any head work to this set up?
What RPM did u achieve full boost?
Not sure what to say in regards to too little timing since u did not mention what it was. Also did you get to MBT when tuning?

Re: Dynoed and no drop in Torque?
Normally when I see a tq curve that continually rises it is because the boost is creeping.
