I had a few questions in regards to your tuning. Can I change portions of the tune before I have you flash my ECU? Reason I ask is because I do not want to raise the rev limiter, but still have the rest of your tune intact. Also is there a flash count built into the stock ECU's? Also doing a tune which I believe is a 1.5 for adding a "high flow" filter, do the afrs really change that much just from a drop in filter from what you have seen? Lastly what is the safety margin built into the tune using 91oct gas? I really don't want to have detonation or pinging problems.

Thanks for your reply
