New xforce now Fuel increase

[SSV8TE]

Just a question for all you 2.5 inch xforce owners. Ive just had the system fitted on my brand new ve ssv ute and in the last two weeks now my litres per hundred is sitting on 13 to 14 per hundred no matter what type of driving. Is this common ? Has anyone else had this reading or is something wrong? Sorry if i sound stupid but questions from people in the know get answers.
Thanks all.

i'd check for leaks, my stock exhaust had a bad leak and i lost low down power severely and economy went to hell

Spot on vx3. Small exhaust leaks will send your fuel economy up the creek. The xforce headers bolts up very nice to their 2 1/2 and 3" cat backs

without a tune when you change induction or exhaust or both, the car runs rucher as the AFR goes to shit.

My economy seems to have gone big time but i do think i have gained power so thanks for your posts as i will check for leaks straight away. Cheers.
