Got a Date with the Dyno! Looking for pointers!
Sounds like a girl from college... got a dyno date on friday, it's a dynojet with wideband. Any advise on how to get the most from this? Should I adjust timing first for max torque and fuel for afr's second or vice versa? My intuition says start rich and go lean, but whats the best way to go about this? The enegine is in a state of rough tune but has not seen an afr reading. Anyone have any thoughts on how long should I expect to be at the shop?
Thanks! Tom

timing will effect a/f so start by verifying a/f are safe, then with a slightly rich a/f adjust your timing in 2* increments. If power increases go 2* more, if power levels off go back to the previous timing and lock it down. Then if your a/f is still off start working on that. Thats my tuning advise

If they don't have big fans, bring your own for the intercooler. Some place a big bag of ice on it.

At the 11th hour I actually found a shop with a loaded mustang dyno 10 minutes from my house and I'll be running on monday afternoon. Actually giving me a little time to work in a map sensor and work out the bugs on the LC1. I'll definitely be posting results!
