This is correct.
He's not being negative, he's suggesting saving money on a tune if going the intercooler route. Cam will need a bumped idle, thats about it.
Cam will add power almost all around, not just up top, but that's where it'll help the most. IC will just be mid/low end torque because all you're doing is adding more pulley and not changing the dynamics of the engine flow characteristics.
This shows you need to do a bunch more researches.
I agree, IC will leave you wanting more.
Nothing wrong with a dyno tune if they know what they're doing. But with any tune, the tuner could have no idea what the **** they're doing.
Totally incorrect.
Intercoolers are pretty sketchy for these cars, and cam requires dropping the subframe most of a foot or removing the engine.
And you guys wonder why GPF is looked at as being stupid.
