I just bought a 2018  Sierra 1500 and the throttle response is slow. This is my first truck and I love it but I would like to fix that. Anyone have a suggestion?

Yup, there is a DIY thread on here where you stick a piece of wood like paint stick or something similar behind the throttle bracket which takes up the bending and flexing out. It helps a bit.

 

I have a tuner that lets me increase throttle response to 20%. You can also try a Sprint Booster, that also gives you better response. All of these are just feel at the pedal, no HP gains of course.

Shim the brake pedal bracket where it meets the firewall.

Made a significant difference for me. Takes the flex out of the entire pedal assembly.

I installed a product that works well for me on my 2017 Silverado "Sprint Booster" P/N # SPRCH011 Sprint Booster V3.

~ $289.99 simple install and you set it to your driving needs.

Ive heard of spring booster, but I have superchip and you can adjust it 20% more throttle response. it doesnt increase it too noticeably but it does a little.

I have sprint booster on my BMW X5 Diesel and its crazy how sensitive the throttle can be at race mode. Mine is the older one where its off, green or red light. 

I would recommend it

If it's an 8-speed, just press the accelerator a bit harder and give it 500-600 miles. Somewhere around 550 miles, mine woke up and you no longer had to get into the throttle bigly to keep it from upshifting below 2k rpm.

I’ll try this out

I had a '15 6.2 and it was not so bad. Well when I bought my '17 6.2 brand new, as I was breaking it in it felt sluggish. Then after break in I felt it was slower and just slow to respond. I followed the advice above about this paint stick mod under the pedal assembly. Well when I got under there and pushed on my pedal I couldn't believe how much flex I had. I loosened the entire assembly and jammed the wood under there and tightened it all down. No flex and VERY responsive, big difference. You can then take it a step further with one of the electronic pedal boosters. I was happy with the improvement and didnt want any jerking or jumping in such a big truck. I have that booster on my BMW and actually shut it off for normal driving as it is too responsive with almost no delay.

Do you have a link for that DIY thread?

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thanks @newdude, guess I'll keep looking.  Test driving so many trucks that have obvious things broken, I'm thinking "if they couldn't even be bothered to fix the power seat," what else is broken".   Just drove a 2021 where the power seat motor was grinding/binding and wouldn't do anything but make a terrible sound.   An owner that puts dents on the bumper, doesn't fix a seat motor, and had spotty service intervals (along with missing major services) doesn't give me the best of confidence.   Amazed at the number of people that will finance a $60k+ truck, run it into the ground, then trade with a loan balance (every single one had "loan/lien reported" on the CARFAX at the last year of registration).

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck

      It varies a ton around me. Some places are still at $5.00 or higher and others are way down into the $4's.   Offroad diesel was $4.02 at the one station I passed today.
