While doing the Initial dyno tuning we also did Turn In Concepts TGV Deletes which were very easy to do. It shouldn’t take even an inexperienced person more then 1.5 hours to do these. With the EJ Series the TGV Deletes required full removal of the intake manifold which is a very involved job and was costly. In this case it is very quick and painless to do the TGV’s on the FA20DIT. When we first did this in February we ran into an issue where the COBB Pro software was not saving the codes being turned off so we ran the car with the TiC Provided OTS map. After some back and forth with COBB the code issue was resolved and we were able to do a quick tune for the TGV’s ony. While there are many skeptics on the internet about these I think the dyno results speak for themselves with this mod. Power and Torque is up pretty much everywhere especially in the upper end as you’d expect. With this mod and custom tuning power went up 21% for horsepower and 20% torque over stock. The TGV alone compared to the custom tune without made gains of 5.7% horsepower and 5.3% torque which is pretty amazing!

Our next step was to quickly install the AEM Intake System on the car while it was on the dyno. While some will claim to make horsepower our results do show otherwise with the intake in this step. With that said the intake will help once the biggest restriction is removed from the system which is the J-Pipe (2015 Downpipe). Regardless here are the numbers, the boost was all over the place but overall power was not made with this mod in the state the car was. Ah well though, it sounds better and looks better IMO then the factory airbox.
