lol, allen gives you an explanation, then asks for a chance to fix the problem and you call him butt hurt? wow. good luck getting the issue fixed. i agree with throttle cracker and will throw in the possibility of a vacuum leak causing this.

I've rode this train before with Nelson performance. I got about 10 retunes until I stopped blaming the tune and found the real problem. A loose rocker on one cylinder was killing power. A tune can't fix mechanical issues.

i couldve took his exclamation mark out of context.

sorry if i miss took your reply farm truk
ray is fixin another ecm to send out so im still hopeful

txsilv. i dont nut swing. I beleive there is more in the tune but
me and Ray believe its hard to pin point areas without a scan cable
and i know i can be a picky s.o.b

I am changing plugs from ngk tr5 to the ngk iridiumlx
and yes the #7 plug has a crack down the side
and im hoping this will help the backfire/pop noise at 4,5k rpm at gear change
im double checking all the basics that i know of before i go to change the
valve springs to rule out valve float (currently ls6 blue springs)
or taking the injectors out to clean them
It didnt do this with the 5.3 ecm

lmao, no i'm not, there's just more to tuning and modifying than you realize. And I actually care about my name and product, so I feel I should explain the situation and open your eyes to other possibilities.
It's just a little hard to swallow when you call the shop and Ray spends a while on the phone with you trying to figure things out and at the end of the conversation he thinks you're in agreement with a solution; then a post like this comes up.

And to clarify, it was suggested that you MAY have to drill the throttle body in order to get your truck to idle IF we put the idle values back to stock and idle rpm back to stock.
IF your truck was idling just fine before the tune, with a cam, then your throttle body definitely has something different about it than the normal/typical throttle body; meaning it's allowing more air to flow and idle decent.
I could go into why drilling the throttle body is perfectly ok, but that's an entirely different subject.
btw guys, it's not the throttle cracker doing it, that is untouched, if the truck is "pulling" with no throttle applied, I know what change is causing this, but adding one small value to this table shouldn't be causing the issue, but it is, so I'll put it back to stock. Just one of the fun things trying to tune for many different variables.

Didn't you just find a cracked plug?
That could very well be the popping you're hearing. Be sure to post up the results when you find it.

That cam and stock drivability isn't too much to ask; it's just that we have seen way more tuned pcm's and have a very good understanding on what can cause issues. I never claim my tunes to be perfect and won't pass up a chance to send out another tune to fix something, but I won't just because the customer asks, there has to be some sort of process.
If I were to do this, we'd be sending out pcm's "to fix issues" everyday!
And guess what, 99% of the time it's install or mechanical causing the problem.

As far as "it didn't do that with the stock ecm" it's hard to explain, but I understand the rule of , last person to touch it.

Just keep in mind, your mods are very easy to tune for, they don't come anywhere close to what we've sent out, so if there's an issue with the truck, keep an open mind.

Quit being a woose and remove all that torque management

redsilv

alright farmtruk i appreciate your understanding.
if you put all the idle values back to stock. What is the difference of me running the 5.3 ecm? I just want the thing to idle better
900rpm at first start then eventually settling around 650rpm just seems a little strong. its 80 degrees outside

Me and Ray are in agreement about trying to lower the idle some and increase the torque management. We also agree that its better to have a
datalog type tune for long distance relationships.

Im sure i have an easy set up to tune for. Maybe just not in the custom mail order type tune. the shipping would add up.
Ray sounded like he could help me out and is sending another ecm
I couldnt talk much since i still have laryngitis, but i tried



Before i go hacking a hole in my throttle body i would like to think
a good tuner using HP tuners could adjust that idle before that attempt was
made.

And no one comments about me getting beat by a toyota camry?
I was embarrased lol

this thread is supposed to be about tuners still recommending the drilling of the throttle body
So i guess this is a common practice with cams 216/220 or bigger in a 6.0
Even with HP Tuners?

I seiously havent heard of drilling the throttle blade in awhile

redsilv

yes yes he is !
Ray said he would just remove it all in the tow haul mode


i did estimate my transmissions survival for about a year.
i did put in a B&M tranny cooler

About the camry thing....there are trucks on this forum that stomp corvettes/vipers/lambos/etc. Obviously these trucks arent stock, but how do you think those owners feel?

you have way too many posts on a performance oriented website to ask such a noob question

That's the best thing about making a truck go fast. If you win against some high HP sports car it just adds insult to injury to the owner. If you loose well it's not to bad.. you lost to a high HP sports car LOL
