Custom tune for Intake only??? You would never notice even the slightest difference. The ECu would adjust and compensate for a minor part like that. Do you know what people charge for custom tuning?? You might see 1-2 HP from this. Not worth it. Temp from day to day would change your HP more than a custom tune for and intake. Let's think about this guys.
The reason they don't suggest them is because of hot air from under the hood. If the Typhoon is designed like the others I have used then it would be a plus for our car. Most K&N stuff is done real well and I have worked with them on many cars when at Eibach.
For tuning sake custom tune when you have done something major, I.E Turbo, Full Exhaust, COMBO Pulley,Intake,Exhaust installs things like that.
Does anybody know where I-Speed gets off charging $900.00 for their Reflash only with Tune? They claim a whooping 15 hp and 45 lbs. Tq.
AP is like 28 HP and 40 lbs Tq. for $645.00 and they developed it here in the USA and a US Spec car. Not from the stinking UK. I don't understand this>>>>
