Why are you sure you'll hit fuel cut? Will you have air filter/exhaust/de-cat? You can avoid fuel cut by porting the wastegate, introducing a restriction to the intake or exhaust (standard CAT back in, or standard air box). I'd say set your actuator to 0.6Bar then use your EBC to raise it to 0.75 - just below fuel cut. Also an aftermarket manifold will help slightly I found. If you want to run 1Bar then you will need a FCD, but you'll also need to ensure the additional boost is being fuelled for correctly. This requires a RRFPR. You can use this FCD/FPR combo but its crude, I would suggest setting the FPR fairly rich then getting a SAFC to trim it down throughout the rev range (should be setup on a dyno.) Will give you a pretty good tune, and is the next best option to an Emanage or equivalent. EDIT: Also, a HKS FCD will be fine as it leans out the entire rev range, which you can then use the FPR to compensate for. Hope that helps.
