Its all good, like Paul said no doubt it will be a torque monster. More boost and ethenol will make heaps of difference. If your spark is failing which sounds like it may be the case, id consider getting a Morris tech ignitor like myself and Paul (I know you already have spitfire coil packs).
And I agree with Micks post.. CRD are a rip, I've seen some of their invoices and they prey on the unknowing. And their tunes are not the best in the business.

Get password, take to UE, get re-tune.. Happy days.. If they built the engine properly, it won't blow up
