Has anybody tried this for increased shift firmness/line pressure? It's made by RKSports. I was going to order maf ends for my 99Z28, but there is suppose to be a resulting drop in line pressure. So was looking for ways to increase line pressure, preferably without using a shift kit. Thanks for any help.

 

Is this the interceptor...a plug in device? you can use it to increase line presure but be careful as it is easy to add to too much.

I'd buy a used HPP3. For about $200 it will be much more usefull and allow you to bump up the line pressure.
