Dynocom dynos are the highest reading dyno, use a dynojet and your numbers will be different

So safe to say your virtual dyno was way off...

Not bad numbers though and I'd say it's right around where i would expect

Numbers look to be in line with other people with the same mods. Peak torque at 5k RPMs is a little strange to me though.

Dynojets are more popular here, but as long a s a baseline is done (which I don't think was done here) any dyno will give you the numbers.

You have to remember a dyno is a tool, and without a baseline its not that useful but its fun to do and gives you an idea of what your car is pulling. Just don't take an absolute number as a hard fact.

Ya the TQ curve is a little odd.

Exactly. Gains are more important than peak numbers at the end of the day. Baseline would be required to know that.

Are those AFR accurate? Would like to see them closer to High 11 low 12.

As far as dyno, only thing important is the delta from stock. Without that it's just a number.

However, for the modifications I don't see them being too far off, in fact I thought they were a bit low. I think there is more left in the tuning.

last 3rd-4th log from OP (not dyno log):



still room for more boost, but fueling is maxed out, so we didn't try higher boost targets.
