The afr was spot on both times i had it on the rollers with a td04... Even with the hybrid! Im grudged to sell it.. I am going for the emanage because i am wanting more boost pressure! I will upload my graph with the td04 tommorow its spot on!! A friend also had one on his before he went forged and made 230bhp with perfect afr, good but of kit for a p+p and i am open to sensible offers
