I'm sure you do have a graph that says 105hp but a stock 2TG would expect to make high 50 - low 60rwkw readings. (ie 70-90rwhp) and the 90 rwhp would be something special !
Take a look through the Dyno day history thread in the under 1800cc N/A Class. You have to kepp in mind that different types of Dyno's measure it a little differently and the readigs are only accurate if the dyno is used correctly.
More importantly tho a dyno is a tuning tool, not a measuring stick. no two dyno's will read exactly the same altho at least the Dyno dynamic chassis dyno's when used properly are getting more repeatable.
