TSX will work but from the dyno Joe Type S posted here;s what was obvious to me.
Keep in mind the same car and dyno was used for all the runs.
With a stock k20a, stock ECU and the TSX header the car made 184WHP
With a stock k20a,HONDATA K pro and the TSX header the car made 200 WHP.
With a stock k20a,HONDATA K pro and the custom header the car made 214 WHP.
The TSX is restrictive that is all I am trying to tell you.
