Hi Tony yes it make a lot more torque than standard problem is deciding which change made the difference as i have extractors and duel 2.5 inch exhaust . since fitting larger throttlebody have not had car on road but picked up close to 90 extra horsepower which motec allowed to be tuned so 75mm throttlebody was as expected . One of the big restrictions with 6.9 the other would be small outlet on stock exhaust manifold . Oh yeah did timming chain at same time as larger throttlebody and retune
