There aren't really any other mods you need to be running low 13s high 12s. I had a similar setup but with an EBC instead of just the WGA... personal preference. Also had a full exhaust w/ 02 housing. My bov didn't add any power.

Back to your car:
With your mods and running that amount of boost you don't have much room to lean out the car with the AFC. You'll probably be able to eek out another 10-15hp with it. With a return line/rising rate regulator and pump you'll be able to up the fuel pressure to get those injectors to last longer. At 22psi or so you'll be able to take out enough fuel to keep her from pulling timing at that boost level. Car will be making pure power. You'll need a tach driver for that AFC and I would recommend a bov, just not the RFL.

The exhaust and front mount will start to become a problem with really big boost but you really don't need anything else to make 300whp on the stocker. I have more but my plans for my car may be different than your plans for yours

If you can just get the AFC from him for cheap I would do that. I'd end up selling the other stuff. RFL for a Greddy or HKS, boost controller for $$ for an EBC and you dont really need the turbo timer. If you like the RFL and want the turbo timer then it's a good deal.


I assume that you do know that you'll need a wideband to tune the AFC so she won't go boom.
