^^ I knew that was coming, almost linked to it myself. Hustler has lower than stock static compression. That is also a dyno tuned map.

 

...and I can run 91-octane on that table with no detonation. This motor is begging to make 350whp.

 

19.5 is what it is at now, and I still have some datalogging and tuning to do. It's been wet here the past couple of days so unfortunately I haven't had the car out. I may still have to pull some timing, but so far I've had a few boosted pulls that have looked really good with this much advance. I do have the luxury of 93 octane here in Huntsville. Like is said in a previous post, maybe the LINK isn't doing a good job of holding the advance at higher rpm. Although I have it set to 19.5, maybe it isn't in fact 19.5. I'll post my adjusted spark table when it's dialed in before I take it for dyno tuning, then after dyno tuning. Hoping to get it done this month.

 

what turbine and housing do you have? Bigger housing and less restrictive wheel = more spark angle.

 

I don't know. Wish i didn't have such a douche bag answer. I've tried looking at the turbo housing, and the only thing that I see is a few of the garret letters. Where is the data stamped on the turbo? It is probably the same one that came with the FM2 kit back when it shipped with 440cc injectors.
