Re: TPI Timing suggestion
Don't expect the type of reply you want. There are just too many variables that are unknown to be able to say for sure that this is "Too aggressive" for your application.
The people here who are truly experts would need much more info to comment.
I will tell you "at a glance" one thing that looks high is the SA in your idle area.
I'm ASSuming that you are idling at about 800RPM and approx. 55MAP.
If you have the materials to datalog you will be able to answer most of your own questions. ie. Knock counts etc. At the very least, you can provide the really brilliant folks (myself NOT included) here with the data they need to answer your query.
One more thing...Read all of the tuning stickies for your application until your eyeballs pop out, and maybe just one more time for good measure. This at least will assure that you will be answered when you ask a question, if not you probably asked a question that has been answered somewhere here about a million times.
