SCT Tuner Safe on Engine?

So I just got the SCT Tuner from AM this weekend. I loaded the 87 performance tune and the car ran fine. Yesterday, while I was driving 2 of my spark plugs detonated. Luckily it wasn't too bad. The mechanic said its because they were the wrong brand, Bosch. I now have Motorcrafts in and it runs even better now. I was wondering if the tune had anything to do with it or just sped up the process.... And is it ok to daily drive the performance tune?

All I drive is a93 perFormance tune. I can get away with putting 89 in from time to time but yes it's def ok to run it all day every day.

I run a 91 octane race tune all day every day. I just got finished up putting in a new spark plug because I was running lean on the number 4 cylinder. Mine was because I accidently put in a Bosch Iridium plug instead of the NGK plugs I have in every other cylinder. When I took them out and compared them, I noticed that the electrode wasn't as long on the Bosch as it was on the NGK. I can't speak as to why it was happening though.

Yea I figured it was safe. I'm thinking it was definitely the spark plugs then. I did some research and Bosch is known for not being good for our cars. Def gonna stay away from them.

Good idea. A lot of people recommend NGK Iridium IXs
