Before the Avensis was a slug now there is decent power. Gains are a good 25% I reckon. Pre boost was where it was needed and now that's sorted. Keeping an eye on mpg but all in all happy days. Thank you Ron for all your help."

"Amazing transformation, box & maf. tired Freelander td4 turned into a new smooth & fast car. Steady idle, pre-turbo torque & more turbo performance. Haven't tried 9 or 10 yet. So glad I tried this."
