I have decided to buy a little Greddy Boost controller from the group buy section.

Can someone fill me in on a little information about these controllers?

Are they Dual or single solenoid?

And do they allow both the Grain and Ratio to be adjusted?

I am already using a nice little Blitz SBC Type S controller but im making a few chnages to my setup and i would prefare by boost to be alittle finer tuned.

Is this a good investment for me?

I would have prefared an Apexi AVCR controller because ive been led to believe they are the most adjustable, nice screen size and Self learning? but the fears of stories ive read about them going bust has scared me alittle. not sure why tho because its unlikely i would use the warrenty anyway, but for the likes of spares etc.

Anyone any advice for me? am i wasting money?

Cheers in advance, Iain
