I am a newbie in understanding engine performance, have been reading quite a bit lately. I am not here to preach from someone else's literature. But so far I understand the following, so please bear with me:
1. Improved air flow efficiency through an engine increases Volumetric Efficiency (VE) of the engine.
2. Improvement of VE results with a corresponding enhancement of torque. There is an almost one-to-one correlation between VE & torque at different engine RPMs.
3. There are conventional mods that one can do to improve VE in an atmospherically aspirated engine; air intake path mods, intake plenum mods, header mods, exhaust mods, camshaft mods, etc etc etc. However you need to select first what RPM range you want the torque to be improved; low-to-mid rpm range / mid rpm range / mid-to-high rpm range? I am guessing you could also do mods to cover a wider range of RPMs but that may get things more complicated & expensive.
4. To take true benefit from VE improvement 2 things need to be adjusted: (a) fuel flow, and (b) ignition advance. The chip modification is required to adjust these 2 parameters.
5. Do not install a chip without knowing what exactly it will do.
So, have you done step 3 above already??? If the answer is "no", do not proceed with chip modification in step 4 right away. You can consult to Ken (site admin) for much better advice on this topic. I am sure Ken will tell you how best to go about VE improvement matters and necessary chip mods.
Cheers
