Getting Used to 2nd Gen Acceration......

make sure the MAF sensor is clean AND have the fuel pressure checked.

 

All sounds normal. You have to floor these trucks to get anywhere. If you don't floor it, you will accelerate slower than grandpa does.

Acceleration is my biggest pet peeve of this truck. Toyota put a hamster wheel engine in a 4500 lb truck. Then bogged it down even more with a shitty axle ratio and the worst geared transmission I have ever experienced. Just about any other vehicle I drive "seems" faster to me because of this.

 

You should drive my 2.7L above 10,000'

 

This is why the sprint booster is available for the Tacoma. To negate the negative bow in initial throttle blade response compared to pedal position. When referenced over a linear scale.

Tundras are much more noticeable.

 

I'm sure it's an exercise in patience!

 

One of our work vehicles is a 2014 Tahoe with drive-by-wire. I got sick of the lousy throttle response so I tried a little experiment. I mashed the gas pedal to the floor and let it back up very quickly, and it did absolutely nothing. I'm not kidding. This was not a fluke - it does nothing every time the gas is mashed for an instant.
If the throttle was 100% linear then the engine would certainly do something with a brief instant of WOT... a burp, a fart... something. But it acts as if the throttle never moved.

 

I never saw this anywhere....I have a 2015 doublecab 4x4 and every once in a while it shifts hard from 3rd to 4th.

 

There's a thread about it in the 2nd gen forum....search for "knocking" and/or "ping". The thread is asking people who have had it done whether it helped or not.

I don't know that this particular TSB talks about hard shifting, but mine used to race to get to 5th gear and then lug in 5th until it downshifted. The TSB changed the behavior to where it wouldn't race to 5th anymore.

 

This is so funny to me. My 08 felt like a rocket ship on acceleration when I first bought it, compared to my 04 DC 3.4L auto. I think they are plenty "quick" enough for what it is. You can almost wheel it like a sports car AND haul stuff home from Home Depot

 

Very happy with the acceleration of my truck. Not sure what others expect from theirs but I think some members here think a truck should be a drag racer. Buy a motorcycle for your rush.

 

Do not expect a heavy vehicle to have a race car response when accelerating.

You want to be forced back in your seat then get a Mustang Shelby GT with a Twin Turbo V8.

 

My issue was the lugging, not overall acceleration performance. You know when you're cruising on the highway and there's a gradual uphill, you start to slow and then the truck realizes "too difficult!" and drops a gear and continues? Well think that...at 10-20mph from a stand still trying to get a normal, cruising start. Not mashing on the pedal trying to get a good 1/4 mile time, and actually flooring it from a stand still made the problem go away.

Sounds like OP needs the TSB fix for knocking/pinging. I doubt it'd help with hard shifting.

 

In the highway the downshift is to come out of OD, which on these trucks do lag.

If you are flooring the truck, your rear tires are going to be spinning. Trucks require slow starts and gradual gear climbing.

This is hard to understand in a forum and without being able to feel it, but what I hearr described is something characteristic of trucks, not something unusual or wrong.

If you don't like slowing down and enjoying life as you drive, a truck ain't fo you. Or maybe a supercharger would be a good mod.

I've driven a truck all my life. I hate instantaneous acceleration of cars (unless I'm racing someone lol). My mom's Subaru Outback has too much for me even. Give me the slow and steady of a truck any day.

 

My 4.0 is much more peppy than the 2.7 it replaced. Very satisfied with the power.

 

That's not what I'm saying.

I've driven a supercharged V6 and a turbo 4cyl AWD before this truck. I wasn't expecting speed. I was expecting the power to tow an F250 out of the mud real slow -- which I've done. I very much enjoy my truck and how it drives now that the ECU is more properly programmed.

What I'm saying is...if you ease into the throttle from a stop (in any car), it should gradually speed up. It shouldn't lug, decrease acceleration and then start pinging. So it's not HOW FAST it accelerates, it's HOW it accelerates. Any car that has a full tank of gas and is good functional shape shouldn't feel like it's about to stall (and no, I don't have an MT) while you're slowly rolling onto the throttle. And for an AT, it should downshift when ascending rather than lug and start knocking until you give the throttle a little kick to force a downshift.

Also, there's no need for it to be in OD at 15-20, while accelerating.

 

Maybe clean the throttle body and MAF sensor, if you haven't in a while. Cheap easy 15 min. fix.
