I heard that this wasn't a good idea on a 215 pump cuz the extra travel will will overshoot the ideal helical opening on the plunger, anyone know if that's true

the plug on a 215 pump will remove more timing than with the stock plug IIRC it takes another degree.

Ok so if my pump is at 17.5 timing now then if i put the plug in it will take it back to 16.5, how will it do that, and what does IIRC mean

on plungers of the 215 pump there is a retard notch, it was placed there for emissions reasons. As rack travel increases the pump timing decreases. with the stock plug the max rack travel you can get is 19mm, on the 215 pumps at 19mm of rack it will take 3* of timing away ( so if you were at 17* you are now at 14*). with the 2095 rack plug the pump will max out its rack travel at 21mm and pull 4* of timing.

Oh, and IIRC is If I Remember Correctly

So would you use the rack plug on a 215 pump ? The 215 only retards 3* at WOT is that correct or not ?
