HOW TO MAKE YOUR LS CHOP-CHOP - HPTuners Guide

[@michaelslack6891]

Ive always loved the way top fuel sounds, which doesn't chop. Thanks for your time and knowledge, Mike in DFW

[@SA8N]

Have you worked with Holley software, I have a dominator and curious how to build a choppy idle tune. Thanks.

[@nickrichard363]

Great chop sounds 😂

[@blairbarham6532]

Really good video. I had to do some digging on the GEN 5 platfrom to figure out under Idle>RPM>Follower>Immediate in the same table as your two Under Over speed tables. They just put the togather on the new stuff. I adjusted it the same amount under the Predicted Tab too.

[@K_M_M_G]

Thank you for the video. At 3:16 did you increase all the tables in green 10%? I noticed you only adjusted one table in the video.

[@postmortemspasm]

wheres the vid of car running?

[@kenshutes6032]

Well done!! You should put out more HP tuners tutorials.

[@williamlopez4934]

I got my truck tune. The chop is driving me crazy on LA traffic.

[@cigardude7]

I have been playing with my idle overspeed/underspeed for the past month trying to get mine dialed in. Teach me!

[@soliman86qatar]

hello mr jack . i need ask you about my track silverado engine size 5.3 but i change engine to 6.2 with cam shaft stag2 , what i can do from everything for new engine . i have hptuner . please i want your honest opinion . please dont forget me . thank you so match

[@Silas28k]

I have a gen 4 so Ima going to watch this video over and over and I’ll try this. I had to subscribe. Man got straight to the point and explained it perfectly. Only question is on the other charts where you multiply it by 1.1 or 10%. Do you do that for all the ones in that column???

[@hardcorehooksets5825]

lmao, multiplying something by 1.1 is an increase of 10% my guy

[@sempergumby8734]

1.1 or 10% ?????

[@Turbogto_guy]

Just did this on mine. 222/233 cam in a 5.3 that was idling smooth at 650rpm....now it chops. I can do a before and after video.....

[@espltdh]

would love to see the comparison

[@ujslost]

Where is the video?

[@Turbogto_guy]

I haven’t done it yet

[@Turbogto_guy]

@@ujslost here’s the video. I did it tonight, just for you. kzbin.info/www/bejne/fn_YZ3lqm5t3b7s

[@Real_tbz06]

You did exactly what he did in this video?

[@Portillo2009]

What’s the max under and over timing you could go ? Iv seen up to -50 and +45 is that safe ?

[@ChefofWar33]

Seems a bit aggressive.

[@unknown9218]

Sounds like Scooby Doo doing chop noises 🤣

[@charliekelley5981]

Buy hp pro today did a cam swap and 3000 stall it had efi live now but the turner live in CA and I'm in nv.. will i be abel to see what he did?

[@roscoeroscoe9059]

Can you do the same on a holley terminator x system

[@joseespinal4513]

Yes

[@joseespinal4513]

Go to advanced ICF - 1D table - then make a timing table offset

[@Busa0069]

My tune in my truck must be really F’d up ! This actually made the idle smoother on my truck.

[@ujslost]

I think his underspeed numbers were supposed to be multiplied by a negative not a positive. I got the same effect as you. But in another video, they multiplied the underspeed by -2 and I got a chop with that one.

[@jdmtake1]

Can you do this with a 2016 Silverado

[@johnnychavez5315]

Can you do this on a fitech ultimate ls system

[@slomango7927]

I know this was a year ago but it’s under idle stability spark

[@johnnychavez5315]

I higher or lower it in idle stability spark

[@robotafflicition]

I wonder if this would work on a 2.2l ecotec car 🤣

[@brapbrapmafucka]

I see no reason not to try

[@510CurtDawg]

I dig the chop sounds!! Lol

[@JacobVillemain]

Lol

[@rubberbandman2540]

bra bra bra bra brap brap brap brap brap

[@Realgp1]

Any ideas how to do this on sbc with efi?

[@TheMoody876]

Make a video of the vehicle running

[@JacobVillemain]

Good idea! I will post a before and after.

[@TheMoody876]

@@JacobVillemain thank you

[@Robert65659]

If only there was a camera to video with, thats higher than 320 dpi..

[@c5vette943]

Will all these adjustments work the same on a C5 automatic

[@cj7911]

Yes

[@angelo_giachetti]

My boosted C6 Vette has a mild cam, 222/228 dur. and I want a smooth idle. Adding an artificial poor idle quality sounds goofy. Why would anyone do that?

[@turkeyboyjh1]

Right I have a 08 Silverado 5.3 tsp stage 2 cam and it idles stock it’s nice most videos I see are shaking like hell

[@miracleandsons]

How would this work on a GEN V 2014 Silverado.

[@isaiah-lava5.086]

Does this work on the p01 i cant find the under and overspeed tables in mine

[@AnglinTexas]

go to Edit, then View, and select "Advanced View". close the engine tab and then reopen.

[@rickboss69]

@@AnglinTexas bloody legend!

[@rickboss69]

@@AnglinTexas will upload BFR and after, 👍👍👍 fully thought w/o a big cam that result was near impossible to crack. shot bro

[@twiztid1fiddy]

Did the before and after video ever happen? New here

[@brkntires]

Not that I can find. Would love to see that too!

[@nicefknmodel2201]

Won't this hurt the engine? Excuse my lack of knowledge.

[@mooremaceo]

I thought the chop just came from a big ass cam

[@ChefofWar33]

It can. But you can make a big ass cam chop REALLY good with this tune.

[@ChefofWar33]

Going too high gives me a check engine light.

[@pontiacperformance1993]

Lol you guys can have the chop off my cobalt I don’t need it
