Thanks for doing this. I wish more people dyno'd their cars before tuning. It doesn't necessarily kill the argument but more data is always good.

Finally got to my scheduled dyno session. These numbers seem to make a lot more sense to me.

I know I said I wanted to do things before/after modding but I kind of cheated here. All dyno runs are after an HKS intake and JB4 but I believe the gains to be negligible for intakes. Blue run is base (map 0), green and red are JB4 maps 2 and 3 respectively.

next saturday I have scheduled a dyno session with a new mods on the car, I will share it once I finish.

Can someone inform me which gear is 1:1 ratio? I read some comments that 6th gear is 1:1 ?

for manual it's 5th. for auto it's 6th. i've also done 4th as well. if it's a dynojet it'll calibrate based on wheel speed and engine speed.

here are my dyno results from yesterday on my A91-MT.

mods:
Catless downpipe ( FI exhausts )
Full exhaust ( MADE Motorsports )
Cold Air Intake ( HKS )
Charge pipe ( Moshimoto)
Stage 2 91 Octane (95 RON)
Bootmod3

All of the runs were done in 5th gear except the green graph which was done in 4th gear.

As you can see there is a huge drop at the end of each run, the turbo is blowing hot air. As I know, the OEM turbo blowing hot air on maximum boost psi (23.2 psi) which it’s a default setting when you flash an OTS map. Also, the weather now in Qatar is very hot and humid, yesterday humidity was 84% :)

It will be less because an A90 ain't as cool. Literally.
