My 2015 LTX_DX starts normal, idles fine and will accelerate to about 7k rpm and wont climb any further. Feels like something is holding it back, it was a rental sled that I purchased could it be programming ( governor ) in the ECU? It has the 2019 flash. I notice the speedo hangs at 53 but gps says 70ish. I installed the TP Big Venom clutch kit this year thinking I had a clutching issue. I replaced bearings last year when I installed a new track. Could it be valves or possible fuel pump? I plan on doing the wobble bearing delete from BOP in the off season. It has 9200 miles.
