Tuner was pulling some logs on a highway run, and in 3rd gear.

I have a mild heads/cam car and, currently, stock injectors.

The IDC was at 58% at 3700, 87% at 5000, and 102% at 6000 (and in 90+ degree heat and 80%+ humidity), and the combo makes peak power about 6300.

I will be upgrading to 42's but I wanted to know..

In the meantime, would shifting at 6000 be ok, or would that be dangerous when the temperature drops? or am I risking something? 42's seem like the right choice?

i would put 42's in it myself. most h/c/i cars making really good hp will usually end up needing 42's.

On a 346 cubes NA more than 30lbs SVO is not needed. Otherwise it only means your fuel supply (pump/regulator) are not doing their job.
30lbs SVO will support 500>550rwhp at proper sustained pressure

Meaning that if you're on the stock pump, you probably ought to at the very least log fuel pressure at the high duty cycle area, and think about a good 255 lph in tank pump at least, with a good wiring approach to supply adequate voltage at high draw


On the other hand, I got a set of flow matched 42s you could make me an offer on.
