I installed a Sure Sidewinder about a week ago and have now driven with it for 100km or so. Most gear changes I'm getting back firing, doesn't matter if I'm pushing it hard or just average slow relaxed changes (BOOM!)
I have a CPe CAI, 3 inch TBE, 100cell cat, ECUTEK already.
Do I need to retune the ECUTEK with the TIP? What is technically causing the back firing from installing a Sure TIP?
P.s. still pulls hard in not harder with the TIP.
