Stock 1.6 owns 1.8s graph inside
Dyno results from yesterdays run. From a 1.6l with minor homemade headwork, stock internals, t25sr20 turbo, water to air cooler, 2.5" exhaust with artech manifold. Ran at 11.5psi.

The car is good after Scott's tune but he had to pull a bunch of timing from all the cylinders and some additional timing from 2 and even more on 3, all this without much power change and looking at the knock sensor readings.
He started tuning with a base tune that is considered very safe and so i do not know why this motor is so detonation prone, that is why i say that the car was a ticking time bomb look at the attached log, that was my last pull and the ecu pulled timing on it, i think that i may pull another deg or two out to make sure that it is ok on hot days, ill defently be runing some racing gas or E85 once i get the flex fuel sensor going and a tune on track days... and will start to build my spare motor LOL

I know how to get RPM signal on Fab9 COP, just needed to experiment a bit... the dyno operator should have been able to do the same with Toyota/GM COP system.
You can manually convert the MPH dyno plot to RPM on the bottom axis if you have your rear end ratio and what gear it was dyno'ed in, and from RPM and HP derive the torque. Sort of a pain in the *** but you can do it.
