i read online that you can get 5-10hp from one of them all tuned up..just wondering if it should be the next step i have every bolt on but wires which are coming in very soon..

i know im gonna need a wideband air fuel gauge just wondering if it would be the simplest route too a couple extra>??

i have the apexi neo in my car,its quite a good little gadget.i have not had mine set up yet but i have been told to expect atleast 8 bhp.
