I've decided im not gonna get them because i dont plan on doing any turbo upgrades in the near future

 

You can change your edge to be 20HP and timing only. That will buy you lots of time for a turbo upgrade. Transmission might be a different story. You can do a shift kit and the GM gov pressure solenoid conversion and hold a good bit more power.

 

$400 for a used set of 150's isn't a great deal anyway... Just throwing it out there
