ITG Induction kit creates MIL light!!!!

Hey all,

I have a 05` S2 Exige and have recently put on a ITG induction kit. I have done approx 1500 miles until the MIL light came on, on the dash. The light remained for about 24 hours then dissapeared. I took the car into the dealer to be on the safe side and mentioned it to them. They immediatly asked if i had an induction kit fitted and they said this was the problem.
The mechanic then put his code reader on and said that the error cod was “P0171” which i believe means “system running lean”
This means the engine is getting too much air yes? I have read various things on the intenet and understand people get this problem.

All engine temps were as normal etc. Should i be worrying for a future problem?
I really want to avoid having the MIL troubling me!!

Can anyone give me any advice to avoid the light coming on or is there any adjustments i should make??

your help would be much appreciated.

cheers

Never had problems with the ITG on its own, apart from once when it had to get a dodgy doze of Morrisons std unleaded. Diet of V Power and it was never an issue.

Cheers for the help evo.

also have to say it was an extremely hot day if that makes any difference.
