I'm looking into upgrading my injection pump. Anyone have on hand experience with the adrenaline pump and the stealth srp-1 pump with stock injectors and a generic tune? What was your outcome And which one in your opinion is the best performance curve. Thanks in advance

 

It is not an injector pump. It is a high pressure oil feed pump. As long as it is pumping enough oil to take care of the injector demand and keep the pressure high enough it has nothing at all to do with the performance curve. I am not familiar with the aftermarket pumps but generally the stock pump is good enough for stock injectors and mild tunes.

 

An hpop upgrade is never a bad idea

 

I was looking into the Adrenaline pump, but after looking at the injector size I want to bump up to, the T-500 will do the trick Terminator T500 - Featured Products
