121%? Jesus......I would go with a minimum of red tops (36 lbs), or call up FIC and have em rejet a set of stockers for you. You get stock reliability and spray pattern with flow matching for about the same price as SVO injectors.
I had them make me some up to flow 42 at our pressure.

Something is screwy man
I have asked this before and it's time to ask again...what else does IDC reading rely on? I have used 2 different mail order tunes and then his tune. They have varied from 78% to 92%.
Are there ways to manipulate it? I was writing it up to fuel filter becoming clogged or something. It's the reason I'm holding off on installing my 799 heads...I thought I might need injectors.
Granted I have the 28#s and I'm guessing 99 had the 26#s but with a cam his size should there really be any way his DC is that high if everything is in order?

If the injectors are suitably sized for the expected FWHP, then the IDC going high is a sign that the airmass calculation is wrong (i.e. VE and MAF tables are wrong).

I just had another local tuner help me out with my tune through email. His first attempt is WORLDS better than the dyno tune I had on there. My car is actually drivable now, & it feels like I've gained 20 RWHP up top! Only problem is, I get NO traction now. ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
Also, my IDC is now down a LOT from where it was with the dyno tune, as you can see from the WOT run I just data logged below. Still not great, I know, but MUCH better than before.

Well he got the idea/specs solely from him, and the actual cam manufacturer is so small that they don't really advertise or promote their own products. How else would anyone know about their cams except word of mouth? He is simply stating that this info was passed through Josh at Spartan. When my cam kicks *** I will give Josh props also, bc I went on his word when ordering it as well.

I read cam threads every day for several weeks & this is the cam I decided on based on all the info I gathered & my goals. I did the research myself. I didn't send my mods to Damian or anybody else & ask them to spec a cam for me (for free especially), & I certainly didn't steal anything from anybody as you seem to suggest. The specs were posted several times in an open forum by Damian. I didn't see anything wrong with using them & saying where I got the idea from, but whatever. Like I said, no sweat at all if I need to edit the title. Just let me know, Damian or mods.

Considering Damian has posted here several times, I think he would have already said something if there was a problem. Don't sweat that, some people are just haters.

The title doesn't really matter. And honestly my "spartan" cam was always said with a little bit of jest, since every other vendor thinks it's necessary to give their camshafts pet names. ![Winky](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_wink.gif)
Back on topic. 99-00 injectors are dookie. I'd recommend trying to pick up a set of 28's for cheap if you could. They can handle about 50 more RWHP before running out of fuel. Most 99-00 cars will max around 380-400rwhp, I've pushed some 28lb'ers to 460rwhp before and still wasn't @ 100% IDC.
Glad to see you're getting it straightened out. I've put that cam in tons of automatics as well as the Cam Motion version which is a more aggressive lobe and larger @ .006. Never had driveability issues. If your current tuner wants to email me a copy of your tuning file, I'd be willing to look at it and offer my advice assuming he's using HPtuners as well.

My DC at WOT at my 6300 shift point is IIRC 94-96%. Is it possible something is wrong with his wideband and it's reading lean? It was a tailpipe meter he used on mine. He tuned me to 13.0-13.2 which seems to be on the aggressive side of lean but since it's a tailpipe meter I thought it would "read leaner" than one closer to the header.

I have the '98 injectors in mine. My cam if anything should be less aggressive and while I have the FAST I wouldn't expect it to make that large a difference.

13.0-13.2 is a hair lean for my taste. I like to run as close to 12.8 across the board as possible with good timing. Running a hair rich with more timing is better than running a hair too lean w/ the possibility of detonation IMO.

I understand. I have logged and watched mine and it runs 28* at WOT and on 91 octane has only ever hit any KR during WOT with a high load in first gear.
I hope to learn to do my own stuff once the Master Tuner book for EFI live is released and I can afford a wideband.
