Lads,

Need to book the car in soon-ish to sort out a little niggle with the tune (methinks its a boost spike in 3rd at around 4000rpm but I'll ask RTorque about that).

My search skills are clearly failing me as I cannot for the life of me find threads about losing torque with CAI's (or I could just be an idiot...probably)

So as the title states,

Should I keep my Hyperflow CAI and simply have the car looked at/re-tuned or go back to the stock air-box + STI air filter?

Car has a Blouch TD05H-18GXT, PW TMIC, 725cc ID injectors, Walbro pump, Grimspeed BCS, AVO silicone inlet pipe and Butler TBE

Makes 226kw/375Nm on 17psi right now but before that was making 153kw/400Nm on 15psi with just the exhaust, pump + tune. (torque spread is better now but I wonder if I can get some torque back from the stock box in giving up some top end?)

Cheers,
Shane.
