I have a Revo SPS programmed with "Stock" mode and 3 different performance settings (91oct - 50/50oct - 100oct) with "Aces IV".
Now in any of the performance settings, there is a massive flat spot till 3200 RPM's then the power hits like a sledge hammer, and if I really have my foot really into it, it backfires, which sounds like its on the intake side. Then when its switched to "Stock" mode the car runs dyno purrrrfect. So my mechanic pulled codes and ended up replacing both temp sensors for the turbos along with both motor mounts.
After picking up the car it ran the same, perfect in "Stock" and massive flat spot in any of the performance modes. UGH! I left a message for Revo tech support and so far radio silence. Any guidance or thoughts would be appreciated. Thx!
