So I plan on swapping in a TII into my GXL, I'm wondering what would be a better option. Just to get like a Apex SAFC or a Stand Alone... I'm looking to get 250 reliable ....



I just want to know what the pros and cons for each are....

 

for only 250hp id say piggyback. get and rtek 1.7 and u should be alright. advantages of it is much cheaper and u wont ever really have to do ay tuning urself. a standalone is much better for performance and is much more accurate with alot more options but can easily breach $1000. so for only 250hp id say go buy a racing beat exhaust, an rtek 1.7 with some new injectors and a boost controller at 10-12 psi. this should easily get u right around 250 and very reliable for less then $1500 overall.

 

Assuming your going S-4 than definately go Rtek with 720, and a full exhaust about 12 pounds should get you close to 250, I just hit 249 at 10 psi with a Safc and fcd, and a stage 1. The Rtek is amazing good, I have seen the dyno and wideband on a rtek car rock solid. If you going S-5 read my thread in the nw section, Standalone for less than a grand." Lots of options,
