I could be wrong here, but maybe a better flowing intake manifold would help .. it may be an illusion, but the stock manifold looks restrictive ... check out the photos of the new Jag manifold its much taller and provides more of a straight shot to the ports .. problem is the 'tour's hood is too low. Also, if the manifold was made from carbon fiber or phenolic (sp) to provide heat isolation .. that would also be of benefit. Thoughts???
