Upgrades
Are there any upgrades I can make to my race XJ That is through the computer or ignition to increase horse power or throttle response?

You saw the photo. Here's how to do it.
Cruiser’s Renix CPS Advance Mod
The sensor portion of the CPS needs to slide up the perforated bar towards the top of the engine.
Mark the perforated bar's top end with paint or marker.
Place the CPS in a vice, just not quite clamping the bar, the sensor resting on the vice jaws, with the Top part protruding.
Place a bolt that fits tightly into the hole at the Top part of the bar.
With a hammer, tap the Top part of the bar and it will slide through the sensor portion of the CPS. Stop when the sensor portion is about 3/8" from the edge of the bolt hole

Can you only do this on renix engines? I'd be interested in doing this to my HO engine. What are the draw backs though
