First ATI dyno #'s , need pulley help
I'm close to your numbers and been there for almost a year. The dyno drums are heavier than your car so the engine was seeing more load on the dyno than on the street.
If Jeff said it's safe then run it, I have yet to see any problems with his tuning and we have dozen or so cars that have made the 3 hour trip down to him to get tuned.
Great numbers and get a rear before try any track runs.

No the dyno drums are not heavier then your car if a traditional dyno jet is used, they are 3000 lbs. And not taking into account wind drag. On the newer 224x model Djets, its only 26 or 2700 lbs
I personally dont ever let any FI car leave a dynojet any leaner then 12.0 at any area that sees even 1 psi boost.
You can still make good power with safe tune (LS1sPower car, I think left around 11.5 to 11.7 air fuel and made 550/500 at 8 psi by 6000 rpm) I think your chancing hurting something if it gets leaned on with pump gas, bit of timing in it and that lean. Putting around on the street and cracking into it a bit isnt going to hurt it, but make a 4th gear WOT pull on the highway its probably not going to like it
We dont want to tell you what you WANT to hear, we want to tell you what keeps you safe

Thanks Granny , I re-posted the other day stating the A/F was flat as a board at 12.0 . Honestly the tuning is WAY over my head , all I can do is trust the man that has tuned hundreds of LS1's successfully . I'm looking into injecting some 'stuff and some larger injectors as these are at 170% d/c ! I didn't even think that was possible . Thanks everyone , Kevin
Yeah jeff at CAm supposed to have a good rep. 170% DC isnt possible though I still cant see that. What is the pulsewidth at 6000 rpm. Ive taken D1SC setups with 42s to that power level and they were maxed but not THAT maxed lol
Hey its making some good power though! Its almost too easy for us now when maxing out a 42 pound injector only takes a pull or two first tie with new mild setup!
Sent you a pm

I'm not telling him what he wants to hear, telling him what my car has done for the last 347 days, about 20 passes at Norteast 1/8th mile track, MIR and VMP. It's best time is 11.03@130 3.73's with 26.10.5 ET Street tire in the back. So I guess wind resistance is not that big a factor at WOT in 4th on 93 pump is it? I am running 42'ers but with adjustable FPR that we had to turn down to get the AF into the 12.X range. It runs fine, tuned on a hot muggy day here in SE VA. So it seems I am stating facts, you Granny are stating opinions. You also might want to explain why shipping weight of a 248 is 8,000 pounds but BOTH the drums weigh less than a Fbody. Is the frame really over 4000lbs on a 248? I'll agree if we were talking about a 224, but we're not are we?
Then again Jeff makes his living at tuning do you?
I do find the 170% DC on the injectors a little hard to believe. Was there a Fuel Pressure gauge on the car durning the pulls? Sounds like you need to upgrade your fuel system up to the injectors.
im going to chime in on the 170% duty cycle on the injectors. i was with him when it got tuned by jeff. feff showed us both on the computer screen 170% duty cycle. so i can say that i seen it with my own eyes. as for the fuel press gauge he has one in the car i watched it on a pull and it whent down to 45 46 psi on the top end.

170 % is what Jeff told me when I asked . I do have a elec. feul pressure gauge idles at 63 , gradually drops to 46 at WOT . Also a racetronics in-tank pump . What else is needed ?

Jeff 'MilkMan' Creech is the man. Tuned my car as well, and my kit twice. (Kit is on SSls1man's car now)
He will tune my next project as well.
I still want a ride SSls1man. lol

Jeff is the man. He is doing my turbo setup on my car cant wait to see my little baby done. Jeff has tuned alot of stock block FIs. Good friend of mine has been running around for 3 yrs making 560ish(D1-SC) to the wheel from one of Jeffs tunes. So I am no tuner but his work speaks for himself. My guess from seeing his cars tuned(which why he is doing my install and his good turn around time). He knows what he is doing.
PS The milkman delivers. Enjoy the ride!

Congrats on the new found power..... I've got my apt. for my tune next monday w/ my P1sc at CAM, so can't wait to see what i pull.
Keep the car where it is right now....you can add to it later. Get bored w/ what you have before you go and blow your motor w/ changes.

Didn't even realize the PCM/software would read/go that high in DC.
I would recommend adding a return line with a FPR to the system . That should keep your pressure up at the injectors. You are really only spraying around 37psi with 46 psi at the rail and 8'ish lbs of boost, if you up the pressure 1:1 using a FPR on the injector you DC will come down and you will be much safer.
Not sure if you were there after the blue 98 TA with a STS system got there or not or even noticed it, that car has a fuel setup I did. I am waiting to hear how it does on the dyno if it wants more fuel or not.
My car has lived a hard life and is still going strong, so I can only go by that and really never heard of any thing bad about Jeff on any board. Yea he is going to tune my other project too, a LT1/RX7 FC I hope to get it down there in the next month or so. Waiting on some Cometic headgaskets to come in to close up the engine.

Just got a new t76 and e-boost controller on its way to Jeff. And the post about your cars tune by Jeff is proof enuff on how well he can tune and on how long that thing has been running strong. Jeff has the motor waiting for ya bud. Its all out and waiting for ya.

. Jeff was trying to talk me into a meth. inj. setup like yours......maybe someday as I'm saving for a rear 
I'll drop you a p.m. later about your fuel set-up , thanks Actually the turbo formula is mine and if thats chris(i1uluz) he put in the fuel system for my formula. Chris will give great details on fuel setups. FMIC on there is cool. I am currently talking to christian about sending a evolution bumper for that FMIC. Synergy motorsports sent that kit. Its good quality kit. The car should be fun when its done. See what that forged 408 will do.
