+===== Overall Cost Considerations =====
+It's true, aftermarket ECUs are not cheap but they open up a lot of doors and remove a lot of the limitations of tuning the stock PCM. Tuning an aftermarket ECU is much more intuitive and much quicker than flashing tunes to the factory PCM.
+If you are planning on getting serious with your build you're going to be piggybacking a lot of modules to give you all of the typical functions you would need while retaining the factory PCM. The costs of all of these begin to add up compared to using an aftermarket PCM that can replace all of these things so there's a good argument for just building the car with an aftermarket ECU right off the bat.

+Total cost if you added all of these modules would range from $1,640 - $1,340. If you went with just the basics: DHP, wideband, and MAF scaler you would stll be spending $660 and have a pretty archaic way of tuning your car.\\
+An aftermarket ECU can eliminate all of these modules while also being much more user friendly and are much more extensible if you want go with some sort of wild inputs and ouputs in the future.
+To use the Holley as an example, switching to the most basic Holley gets you built-in:\\
+- wideband based fuel self-tuning\\
+- boost control\\
+- speed density tuning (Throw away your MAF)\\
+- anti-lag / launch control\\
+- run any coils you want to\\
+- customizeable advanced tables\\
+- customizeable inputs and outputs\\
+- extremely fast reads and writes\\
+- live tuning for things like fueling and timing\\
+- expandable with Holley's CAN bus\\
+- much much more\\
