New guy who just bought HP tuners, got a 5.3 Silverado recently cammed and it has a very rough idle
I bought hp tuners thinking i could tune my own vehicle but im am very lost so im asking the forum for help
As title states truck has very rough idle and almost wants to die on me when i come to a stop, if some one would be kind enough to tweak with it

5.3 Sivlerado
227/235 .614//.621 113 lsa
4.10's
cold air intake
no cats
straight pipe

 

That's a big cam for a stock converter. It's almost the same size as my cam and it would surge bad when coming to a stop. Is your throttle blade drilled?

 

My TB is not drilled, would a converter fix that problem?

 

Yeah you need a converter to fix the surge at stop lights and what not. Some people drill the blade to help with tuning with big cams like that. I'm not a pro by any means so hopefully someone more knowledgeable will chime in and help ya

 

converter is not gonna solve your problems a tune will though cams not big enough to drill a hole ! might wanna roam around hptuners website for answers to tuning or get a hold to a sponsor or someone who does tuning pay them and see if they will help you out


on the converter issue though, your cam's power band would definitely need a bigger stall size, depends where the torque peaks though

 

Was under the impression it was tuned already but makes sense now

 

I just need it to idle right thats all, I guess some should tutor me on how to tune my idle

 

Or if i could get a link to a thread that can lead me to idle tuning, ive searched already and no luck

 

theres more involved than just getting it to idle, its amazing what google brings up

Idle Tuning How-To & Guide (w/pictures))

 

Got quite of bit of reading to do and ofcourse there mores than idle to that but its a start
