giac's (and others) tunes are tied to the 95040 contents. you must dump the original 95040 contents and manually change the 2 hex values and checksums while leaving the rest stock and reflashing it.
Well if thats the case I'll have a look at the original bin i read before flashing the immo off file.
On another note, can someone explain me why they gooped the 95040 ?? Is there any vital info to get from there? ( other than what you just explained about the immo file tied to the flash )
