I have some questions about the 3.4 setup.

Right now i am running a 3.4 with an intake and 3'' catted dp.

I am not hearing any pinging at full or part throttle.

I know everyone is going to say "youre crazy get a plog, plugs and tune".
If i don't hear any pinging, does that mean im not getting knock?

Also do i need a smaller belt with the 3.4"? At full throttle, the boost gauge reads full.

I dont really want to go down a heat range with the plugs if i dont have to obviously since it will take forever to do.

I also plan to get a 180* thermostat on there before i run it any longer, however it is staying at like 190* even with me tromping on it.

The reason i have intalled the 3.4 without the plog or plugs is because my dad had a 2000 gtp, installed a 3.4, thrasher box, and catback and ran the car like that for 80k. At 100k it got a bunch more mods. The car now has 175k and is running good.


I guess i don't need a smaller belt?

I am working on getting a plog but i cant find one. So it really worth it to spend the hour or two changing plugs?

Is the tune to make it run better, or gain power? Also do i need to buy one of those $200 aeroforce gauges to read knock?

I don't drive this everyday so dont be too worried.

thanks.
