Order a new silver 25cal Impact today. I'm told delivery in July. Was wanting to give the new Daystate Pulsar a try, but fastest it will shoot the 34gr was 715 fps. With the electronics it only has high and low. No other adjustment. So will give the Impact a go. Interesting, I would have thought production would have been catching up with demand. It's surprising that the production of the wildcat hasn't caught up with demand yet. Be interesting to know just how many Wildcat and Impacts FX produces per month. 
 
If you still have the Daystate Pulsar and want more power contact this seller(Jan) on ebay:

I installed the board in a .177 Airwolf. It shot 11.5 fpe and 18 fpe with the original board. Now it shoots from 8 fpe all the way to 27 fpe. 12 different power settings compared to 2 with the original board. I had a problem and Jan could not have been more helpful. He even offered to take it back for repair. Thankfully it didnt need to go back and my Airwolf is shooting lights out.
 
It is because of the demand the Impact has suffered such lack of quality control, they are simply pumping them out too fast. That is why I will wait until things cool down and perhaps there will be an Impact mk2 like the bobcat. I can really see myself holding the Impact .25 with euro shroud in the future
