They had an open dyno day near me 2 pulls so I figured WTH why not. Stock 2014 IS350 AWD made 251hp to the wheels.

I'll try to get the sheet scanned in. I'm having trouble with my scanner.

mustang dynos read a little lower

Good to know, are you planning any performance Mods. Thanks for sharing.

Yeah it's cool the car did about what I expected. They didn't have the wideband hooked up so I didn't get any AF ratios. There's some rippling in the power graph, so I suspect the factory grounds could use some improvement. I'll probably go back for some more pulls with additional data points.

is that good or bad?
anything to compare it with?

other dynos should read 270ish, mustangs read lower so 251 sounds in line

Well there was a 2014 370z that ran after me. He put down 270. I think those are rated 335 to the rear wheels?

Weighing options for now. I'm not looking for huge gains, but 50 to 100 would be nice.

I don't have any experience with direct injection used on these motors. I'm not sure if we can just install bigger injectors like port injection motors. This is my first car with CAN. All my other cars were OBD1, 2 or carburated, so I need some updated tuning tools.

I want to see the AF ratios to look at what the stock ECU is doing. The horsepower falls off a bit as you get close to redline. I've seen on other toyotas I owned that this is due to the car running a little rich on the factory tune in open loop.

It's about right considering it's an AWD model and a 17% driveline loss.

My scanner is giving me fits, here's a blurry scan:
