Hello Guys.
Just purchased my 1st WRR and already bought a Q4 and Wiseco Fuel Programmer (new but cheap).
I have a lot of jetting experience so I can dial in the "offbrand" Wiseco I feel without too much trouble. However I am thinking about returning it and buying a PC5 Programmer so I can gain the performance gains of advanced timing, etc (ECU programming), not available with a standard "electronic jet kit" type fuel only programmer. Sooo, I would like to know what are the HP and Torque gains by also advancing the timing and performing a full "tune", vs adding fuel only. ANYONE????
Many thanks!
