14 Thunderbird Lt backfire with Remus exhaust fitted. Mostly on declines and deceleration. Remus claims no remap needed. Although I did tighten all exhaust connections Remus recommended. Seems like it might be lean condition. Just need some input from all the gearheads out there. Do not want to do any internal damage.
Remove and blank off O2 sensors. Remove and blank of SAI. Will sort out the probs with aftermarket pipes on Trump Twins!
Probably not! Take a look at the TTP tunes and SAI,O2 kits https://www.triumphtwinpower.com/america-speedmaster-efi-tunes.php Probably cheaper and easier than a power commander
Ended up installing booster plugs to control airflow and fuel adjustment... it worked great...no more issues
