It was the first vehicle I owned with drive by wire, and at least early on, before the transmission recall, I wondered if the input from the drive by wire was too fast and confused the mechanical parts responding to the drive by wire information. I also felt there was a change once I changed from Z-1 to DW-1.
Same here, but I will share a experience that I recently had.
My RL only had 38K miles and it was babied as it was in mint condition.
I've had many vehicles in my lifetime that had 185-300 horsepower stock.
I did enough research to believe that Honda didn't smudge the HP numbers on the RL, but I wasn't feeling it.
I know it's slightly on the heavy side, but I've had many trucks.
First let me state that I don't believe in "fix-in-a-can" products and I've used many injection cleaners with no noticeable results.
I usually add some type of injector cleaner once, at most, twice per year. Once in the spring/summer and maybe again in the fall/winter.
So I've tried many different "cleaners" in my lifetime.
Since the rig was babied, it felt sluggish to me. I wasn't feeling 250 HP at the throttle.
Long story short, after several recommendations from friends and fellow gear heads, I decided to try another injection cleaner.
The recommended product was 'RXP Gas Kicker'. It was $6.99 at autozone and 1 x 2.5 oz bottle treats 10 us gal.
I just filled up so I grabbed 2 bottles and dumped them in right there.
It wasn't long and I was surprised at the throttle response and HP gain that I was feeling.
I figured it was a octane boost so I figured I would wait until I ran that tank empty and at least another tank without the additive to make a decision.
Conclusion, I'm on my 2nd full tank of gas 'without' the RXP product and I'm still enjoying the throttle response and now feel that 250HP might even be slightly under rated.
I have no affiliation with this company. I'm just sharing my personal experience and YMMV.
Link to the product at autozone.....Here, but I figure many places may carry it.
