When to safely drop pulley size?

[2007GPGTSC]

I have looked everywhere in my area the highest octane I can find is 91 w/o ethanol. I have literally searched probably 25+ stations looking for 92,93 ect.. with no luck although I will always atleast run 91

When your cammed or intercooled. Other mods are kind of pointless anyways

Yup. What exactly do you mean once you IC or Cam other mods are pointless?

Really? Based on what?

few simple rules... More air in = more air out, so you cam or pulley drop, you had better fix your flow/exhaust as well on these engines. More air in = eats more fuel too... You better tune it or lose any gains you should realize from your investment. You mod, you'd better monitor it or save some extra $ for another engine... You go faster - you better change your braking and stop over shorter distance. Depending on speed, maybe a cage too. You race, you better tighten your suspension, better rubber, etc..., etc.

One thing ALWAYS leads to another, and your simple - other mods are pointless - is very vague and irresponsible to say.

Have a nice day!

I have similar mods plus a tune from Overkill and I run a 3.5" on my 2007 GT with no knock. I however do have 94 octane and an in car tune.

Having a tune on the 04-07 SC cars plays a huge role in this.

They command way too much WOT timing for their own good.

I just tried to downvote this, I've been on reddit too much.

That's one of the dumbest things I've read all day.. if you open up the intake and exhaust, you can benefit from increased boost.

While it's being talked about here, is there a reputable Torque or similar app for iOS? I couldnt find one when I looked, but that was over a year or 2 ago.
