Just an update...had the new intercooler and VF34 installed and tuned, dyno of before and after attached...seems as though VF28 had more power earlier in the rev range. Overall not a great deal difference between the turbos...

It needs more than 1.4bar of boost............ That plus it's 30 odd degrees outside which will give you a lower figure........Still 14HP & 13nm more power.

Ps you have 2psi drop in boost from peak to redline. What boost controller do you have?

What did Sean say?

Hey Rossco,

I don't have a boost controller, it was not recommended when I first took it to ASG. Sean didn't say much- just said it's not a huge improvement but VF34 is similar to a VF28...what do you think I should do?

P20, more boost and rev that fucker!

Good advice!

I think I will try somewhere else for a tune...anyone know anywhere else besides Mao that can tune power fc ECU? I've heard good and bad things about maximum Motorsport...any recomendations?

All Star Garage can do them

Your best to keep with ASG and get Sean to fit a electronic boost controller to your car.

No need for a boost controller with the Power FC - it uses the factory solenoid & Map sensor.

It needs more boost wound in however. Sean conservatively tunes all GC's at 1.4 bar.

Turns out there aren't many tuners that deal with powerfc and my options are limited. I might wait a little bit and go back to ASG and talk to Sean. I will say that the car definately felt faster and more responsive with the VF28...
