So you bought a crate motor from LC.
I don't think you installed it.. Whomever installed it should have been in charge of timing it correctly.. Timing is pretty basic stuff and if they switched the distributor and all that other stuff over for you, it's PART of that service.
The bad news is that strokers don't like factory EFI. I wonder if LC told you this when you ordered that thing for $4-5k? There is an aftermarket (LC Engineering) solution - but it's another $1500 on top of it.
There are various ways to tweek the existing EFI, like manipulating the resistance of the engine temperature sensor... This is a patch, better than nothing, but I'm not sure it will work out well for ya..
Get the timing worked out, all the engine codes straight, and then let's talk tuning...
I'm in Austin, TX, btw..
