Well, I ordered the exhaust (deleted the CATS and rear silencers only), large bore throttle bodies and replacement ECU chip from AJ6 Engineering for my 1994 XJS 6.0 V-12. Nice bit of kit. I installed everything without a hitch and I must say I'm very pleased with the outcome. The sound is better and I can tell a difference in the acceleration; it just seems more responsive, like a Jag should. If anyone is interested, check out AJ6 Engineering's web site. Roger Bywater is easy to deal with and his instructions are easy to follow.
