it depends most on your cam choice, as the 94-95's are picky...they like a certain lsa.
When i changed to gt40p's/explorer intake/crane 2031 with everything else being the same, when i got a chip and a tune i was only able to get 6 more total hp, BUT i needed the tune for the idle!
if you turn the idle up you could probably get away with it not stalling, but it will mostlikely not idle like stock.
