Just got a tune, need help explaining what the plots mean.

No two ways about it the TD04 is stupidly small. You do get that the cfm between a TD04 and VFanything vary wickedly? As in TD04 - 360cfm compared to VF - 450-490cfm roughly. Back to back on my V5 non sti @ stock boost VF23 came on faster/stronger and had more everywhere over TD04. According to web info which may or may not be accurate some of the TT turbos flow more than the TD04.

Main thing is its good to see youre happy with it.

The beauty of the little turbo is that you get awesome early response from it. You\'re getting max torque at 4491rpms and 90% max torque at 3500. That should give you excellent push driving out of corners.

Never had them on a dyno only from driving perspective but imo VF23 was better all over. That being said I would expect with the VF having better flow capabilities that it would outperform the TD04 regardless although it might not hit max torque so early but have more if you get what I mean. This is all in my theoretical world of maybes as I cant read a compressor map and dont have dyno graphs to back it up. In forester and V5 it felt like the TD04 took ages to wake up then ran out of puff right after it started.

Cornering is what I enjoy most

It\'s appears that evowrx is having a geek out all by himself???

lol.. pretty valid points regarding a bigger turbo...

I do agree that for very little sacrifice to spool up times, you can get a turbo that has better peak airflow.

Though, its not something on the cards for now, and the motor is most likely staying like this for now.

Anything more would involve bigger turbo, bigger injectors....

As a side note, living in apartments suck when you intend to work on your own car.

Will be looking at sway bars and ALKs...

I think my point was finally understood being in my case it wasnt a sacrifice of anything it was pure gain at the same boost level. Very high tech geeky stuff for sure.

Who tuned the car?

Its in the bottom left of the dyno sheet in the first post.
