Overkill Will Tuning God

How many people here actually have a overkill tune that had or have a tuner or have tuned in the past, and actually looking through the tune for this "magic"

My 07 GTP started with an Overkill tune. My HPT couldn't connect to it.
He sent me an 05 PCM with his tune so I could do the tuning on my own. Couldn't read the stock PCM

Since I had no IC and a much smaller pulley than his tune was ment to run 3.0), it ran decent but needed a lot work to work on pump gas and meth with no knock.
Trans shift was also conservative, and that makes sense for a generic tune sent by mail.
I had to make a few changes. That is to be expected because I had a different set of mods.

The Overkill tune once modified by myself to run my 3.0 S/C setup and eventually my 2.8 pulley now runs my turbo setup on my 07.
Very little changes were needed for my turbo kit to run perfect. Car ran 12.0 @ 117 which isn't bad at all for a street tire heavy FWD car !
 
First mod I ever did on my Gold GTP was a mail order tune from Will, gotta say it was like night and day difference. The Overkill PCM is still in Goldie and the new owner swears she has more power than his GTP, which has a few bolt-ons. I'm not taking any sides, but I will say that I'm glad I purchased a tuned pcm from Will. Every time I went WOT, I never saw a blip of KR. Being owners of a dead platform, we should be happy there are people and vendors out there still willing to help out. They could easily move on.
 
As I am the person who started this thread, it was meant for those here in BC who would like to contact me, as I am trying to set up a Tuning Day with Will from Overkill.
It was not meant for anyone to criticize or condemn his Tuning ability which in my opinion speaks for itself, with that being said if you have other Tuning preferences which
are not being met by my attempt to satisfy and assist those that would like to use Wills Services I would appreciate that you post your comments elsewhere.
I am only interested in those like myself who have used Will's services and are happy to do so again.

You posted to a Internet forum with .Com at the end not .CA. there are many other people who can tune that don't have kr at wot or any other time. It's not a hard concept

If you think kr is an acceptable design criteria for a car gm released into the wild then you are just looking at this through jaded glasses. Gm spent millions tuning this car and they had millions at stake satisfying the customer as well as preventing warranty damage. Ive driven and scanned my gtp for over 100k miles with a stock tune and a stock exhaust with a ubend delete and never found any significant knocking. Same goes for a handful of other factory stock gtps ive scanned.

I'm going to assume you're trolling now. Seeing as how I can't recall any stock gm vehicle I've ever scanned that doesn't knock.
My 01 gtp made 205whp stock and knocked.
My 97 gtp ran 14.6 stock in the middle of summer and knocked.
My ls1 gto knocked with the factory tune.
The countless other l67/l32/l36/l26 cars that I've scanned/tuned all knocked while being bone stock.
Hell, my $60k ecoboost that I bought brand new, knocks some.

So, if any knock is not acceptable criteria, they did a piss poor job of enforcing it.

Nailed it. More than one way to tune a vehicle obviously as long as its not leaving a trail of grenaded parts and the vehicle runs good what more is there to ask for? The only way to settle which tuner is better would be same vehicle same mod list tuned by each and see what happens on a dyno. That is next to impossible that its ever going to happen.

Dyno only tells half the story anyways. Sure one could tune it to belch out some big number but have poor driveability. The balance between the 2 is key.

Strange reply. But this is .COM. LOL

Re-read post #1. It went sideways with post #2 and kept rolling.

Yeah, because all they know how to do is fuel wash a car to keep it from knocking.

HERE YOU GO BUDDY, RUN A 3.3" ON THIS DOWNPIPE ONLY CAR. 10:1 AFR GETS NO KR.

WHAT?

THAT ISN'T HOW YOU'RE SUPPOSED TO DO IT?

WELL, IT DOESN'T KNOCK. IT'S OK.

very true. I shouldn't assume on that one.

I don't desensitize knock sensor voltages, reduce attack rates or increase ignore times, or do any other funny business ("magic") to artificially reduce the amount of KR the PCM would normally implement. I've NEVER done that, ever, on a 3800 tune.

I never accused anyone of doing that. But I am well aware of that being done to cover mechanical issues.
 
And for the record, if I cared to look back through years of archives...which I don't...

"someone" has said he has deactivated knock sensors.

Along with another guy back when this forum first started that used to spray the crap out of his car.

But; that's in the past, right?

do it.
 
A. these are mass produced engines, rotating assembly's have been found to be 7 grams out of balance due to "gross" balancing of engines and parts bins.
B. production differences are massive, damn close for 100,000+ units...but ****ty. head castings with port obstructions, cams with lobe lift all over the place as the grinding wheel wears...
C. carbon buildup in the chamber/ports, injector wear and tear on top of a fairly large variance, oil past cyl 4 rings (the cyl4 windage tray issue), pcv recirculation of oil vapor as the rings wear (not like they gapped em) but more than that the wear is inconsistent, similar mile 3800's and i get over 8thou diff on the ring gaps at nearly 100k the cam is nearly 2* retarded with the chain/sprocket wear.
D. SENSOR production tolerances/wear/skewing, NB O2's, MAF. buildup of crap on "trusted" sensors, skews readings and changes fueling.

all this is why you ended up with some factory freaks, and some factory dogs.

i dealt with a factory dog, 02 gt, knocked na, knocked sc'd, even with headers, exhaust, intake and me porting the new heads...still knocked.

changed out the shortblock to a different NA shortblock (98)

KR gone, no changes to tune, only thing changed was the shortblock, reused the 02 KR sensors as a test of my theory. OE L36 kr sensor tq.

sometimes yer just ****ed.

but i heavily agree people run em too rich. its horrible to see a low mile motor with polished bores and no crosshatch to be seen.
 
I admit I know very little about tuning. What knowledge I do possess comes from people like Will and DH among others who had helped me figure out random issues along the way. Everyone has different methods of coming to the same conclusion. Whether a tune is done PROPERLY is for those whom know more than I do. The only people who are experts at this are the ones who originally wrote the code. Even the magical tuning schools only teach you one or two ways of coming up with a result...and even that is based solely on personal preferences.
