After the y pipe I do already have a QTP cutout.
What do you mean by colder plugs?
with my truck as it was I was making 300rwhp on dyno. That’s with 3.92s and 8 speed as well.
I don’t have any gauges or monitors yet.
Colder heat range plugs. A colder plug transfers heat faster compared to a warmer plug. The colder plug helps to keep combustion temperatures down to help prevent detonation.
Depending on boost level the stock ones might work, if your 5psi or less. I would recommend 1 step colder if you’re going for the 6-8psi range.
