I just bought a 2004 XJR. I have ordered the intercooler pump parts to upgrade those components. The car is already fitted with intake and catback Borla exhaust.
i would like to do a pulley swap and have the ECU tuned. Is there a setup that is safe and reliable? I am
not trying to race, although I would like to play occasionally. I am looking for smooth power delivery.
The ZF was recently rebuilt 5k ago, and the engine is just under 150k. Any help would be appreciated
