I've done this before. 1 tooth off on a timing chain.
The Firebird was supposed to make 360+RWHP ended up making 267 RW when we tuned in on the dyno. Darn thing ran fine though, you would never know!
My bet is that you're more than 1 tooth off. Don't mess around too much if you're that far off the engine is an interference engine you could mash the valves.
