Default Hero C5 or generous dyno?

Went out and finally had the car tuned after 4 years of it running with only a Corsa Xtreme catback and vararam intake as only mods. It definitely needed a tune because the transmission is weakening so we changed the shift points and it does seem to run a lot better and is more direct.

However, I haven't been able to get on it in this weather. Was also running very lean. Car is an 04 automatic. I was very satisfied with seeing 309whp and 316 torque out of our baseline run but was pretty shocked when we got 334(it dynod higher earlier) and 356 torque.

This was done on a dynojet. Are they generous or is it a hero?

I was at 325/335 with a cold air, tis and a tune on an 01 6m. Generous dyno or not that gain from just a tune was worth the price of admission.

Good job OP. If you're not running a catch can that would be my next mod. You could squeeze out a bunch more. Ask me how I know

Whether or not the dyno was generous or not, it was generous on the baseline pull as well. Great gain for a tune. Go run it at the track and if it traps 110 or so, you've got really close to the horsepower shown.
