I want to run a 75 shot. On 91 octane.

If I use the ol timing tricker, and run tr6 plugs, would this be safe or ballsy?

iirc the ballpark is usually 2 degrees base, then another degree per 50 right?

Every car is a little different, plus it depends where your n/a timing is at. But with that said 2 degrees for every 50 is the general standard

Stock tune so far. 2002 ls1 f body. The "timing tricker" should pull 3 on stock tune. I could probably find some 93 for when I wanna spray if need be.

What exactly is the "timing tricker"? Is it that relay thing that tricks the ecm?

Yea...I know it's ghetto, but it seems to work from what I read

No I agree...it does the job for the fraction of the cost. I know a few guys using them and they've worked just fine. But if it were me I'd run the br7 plugs just to be safe.

a TR6 is a projected plug. If you're going to spray then i recommend using a non projected tip plug like a BR7. You can probably get away with what you are wanting to spray but we always recommend getting tuned.

Oops, typo. I meant br6's. I've read that a 6 heat range is good for under 100 shot, and above that you should go with a 7. Car will still be mainly street driven and only be under spray when the pesky pony next to me is just a little to close for comfort.

Considering that it's street driven, would you still recommend a 7 or is it going to be too cold? Or maybe just switch to 7's on race day for that extra vote of confidence safety wise

For reference I went from the tr6 to the br7 and noticed no difference whatsoever in my n/a performance or the drivability.

br7ef will be fine for daily use. I daily on b8efs.

What is the stock tune timing? If it's in the range of 25 and pulls another 3 down to 22 I think 75 on 91 should be fine. I would still put a couple fresh plugs in and make a hit to check the plugs.

Same here. No issues whatsoever
