What would be a conversative timing amount at 195kpa?

How are you setting the tune up so it pulls timing by manifold pressure? My timing table bottoms out at 1.20 g/cyl basically at any boost level so the last row of the table is my timing in boost. Is there a timing retard table based on manifold pressure?
I think you are conservative on your timing by the way.

also EFI Live has a table i use to help with high IATs/hot starts. Once I got it dialed in, i have no issues...
Technically I'm on E48 now, although I still consider that superior to gas and meth.
Also, if you meth pump fails and you have the timing increased you've probably just blown your motor. The way I see meth usage is as a safety net, not as a performance increaser. But that's just my opinion. Even with E85 I never treated it as a superior fuel and drastically increased the timing. My goal is to keep my stock junkyard motor alive and keep playing.

Thanks for the replies, i think i will keep it like it is now, and just roll with it...

My AEM has a failsafe wire just for that reason. If the pump goes out, or there is a short, or the fluid level gets too low, ect. then the failsafe will shut the boost controller off or however you have it wired. I plan to wire it to the boost controller so if there ever is an issue, it just drops boost down to the spring pressure. I thing that is 5.5psi for me right now. But you could wire it to pull timing or something like that too.
That EFI live table is cool for sure.

Speaking of meth comsumption. I have been using about 3/4 of a gallon per week. I fill up my truck once a week with ~21 gallons. Sooooo i think that is pretty decent.

I thought about going to the dyno the other day but then i realized i dont care that much to do it. I also thought about going to the track the other day but then i decided not too.
Call me old and lazy. Just surround me with cats and my AN fitting collection and i am happy

Thats definitely a great failsafe for the turbo guys. For me I have a good idea what it will be every time I step on the pedal. I guess it would be nice to pull a degree of timing if I do end up seeing more boost due to weather changes etc though.
As far as the timing. I would think you are on the very safe side right now. I spray a very similar amount of meth with a single 15, and I run 15* at what was a peak of 200 KPA.
