I have a MY01 WRX which i puchased stock. My plan was to do all my mods, and then get a tune to maximise all the upgrades.
I upgraded:
3"
TBE + Up Pipe
STi TMIC + Y-Pipe
APS CAI + Silicone Intake
Walbro Pump
After all those mods, it was running rich and it came on boost very hard, and then kinda lost boost towards the top of the rev range.
Eventually took it to AllStar, had to wait a while, as Sean was tuning someone elses car, got my car on the Dyno about an hour later - Didn't really want him to rush his tunes!
They have a very nice setup and a brand new dyno.
First run yielded a poor 120kW with all my mods due to it running rich. 3 runs later and about 20 minutes, we had it at 165kW and 290Nm on the TDO4 @ 17.5psi.
This was the limit - I need a boost controller to go further apparently.
Took it for a drive afterwards as they do, and it felt nice, real nice. Drove home with a big smile on my face. It definitely felt lilke i had more power, coming on boost nice and clean, and it feels like it punches hard all all the way up the tacho.
Very happy Verso customer here, highly recommend the guys .. top blokes who work absolutely crazy hours!!
Ask if you want to see the dyno graphs.
