why are you running so rich? it appears your AFr is 11.0 for the majority of the run... any idea on how much timing your running... Also i think your probably maxing out the injectors whether trick flow or your tuner says so.... hell my H/C 4.8 maxed out the stock injectors....

Nice numbers for sure! But I agree that there's more in the setup. AFR should be in the mid to upper 12's on a N/A setup like yours. This will yield a big gain. I'm also curious about how much timing you're running, and what your injector duty cycle is.
I bet it's an animal on the street.

15-16mpg w/ mixed driving, i like it ok on the street, but the stall combined with the low torque/peaky small cube n/a motor make it a pretty dull drive unless i find myself in the right gear and really put my foot into it. if i had a do-over, i would definitely go for more cubic inches....but i have a low milage truck (35,000) and wanted to build on what i have
good points, i don't have the answer, lmr scheduled me for a friday (thier busiest day) and my truck is stupid when tuning--have to unplug bcm when flashing pcm, and then sometimes it still doesn't want to take???? The guy tuning it appeared to have a cold and seemed to be irritated with how my truck was acting. maybe on a good day, he would have been able to nail it...
i don't have the answers, i didn't want to bug the tuner more than i already had, see above! lol The truck feels best when punching it at 30mph, catching the top of 1st gear and barking the tires when it shifts to 2nd

Yeah there more left in her, the cam is small but ok, with an upper 220s cam and a spot on tune 400 should be vary doable, those heads are about the best you will find for a 5.3.

Well last night was dissapointing ti say the least...14.10 @ 98.8 was the best i could get out of her, 2.2 60' trying to drive out of the hole without too much spin. I know i need some sticky tires, but i was hoping for 13s street tires/12s on slicks not 14s/13s. weather was mediocre at best 700 da, very humid...and i did leave too much gas in the tank...a 13.9x maybe possible on a good day. At least i was faster than the 6.0s that were there

Thats not a bad start but there has to be more in the tuning or something, I could understand the time with your tight converter and street tires but the mph should be higher, I ran 13.4 @ 100 with just a 221-221 cam and a 3600 stall and boltons in 2500da. Whats your trucks waight? what shift points?
