did you ask jon ? i found there not very mild with the z22se ecu as there's no control options and you have to run at 1000rpm idle
with the AEM infinity i fitted there are options to smooth it all out and run down at 750rpm without the loppy effect but you do have to dial them in properly when using the keyed 2.2 sprockets on them it just makes the down pipe glow
Yer there deffo not mild I’m on Dutch peter has got them running bang on and I idle nice around 750 also but still a bit loopy I’m just not happy with how far up Rev range my power is.
When I figure out what cams to get I’ll prob chuck em on cobolt forum as Jon mentioned
