What are yor other modifications? You posted something else in Zetec tuning, I responded to about the Crane Stage 3 camshafts, here's some quick info on those cams:
Radical Street/Strip profile. Manual transmission w/headers. CNC Ported heads w/port matched intake. Increased Compression recommended: 10:5 - 12:0. Excellent Power naturally aspirated PLUS super nitrous cam or supercharger.
RPM range: 3,000 - 8,000
If I remember correctly you didn't mention any of the above mods in your other post, where you had posted your mods.
No you cannot run your diablo chip with nitrous, unless it is a custom burned program designed for nitrous usage.
If you want do it properly here's my suggetsion:
Contact one of the vendors here and talk to someone knowledgable about building a setup for your application.
