Your looking at a minimum of a 4* timing pull with that code set. You should have coughed that up earlier that it had a code set.

It just came on though. It had come on before the tune so I replaced it right before I got it dynoed and it hasn't come on since. It didn't come on during the Dyno runs that I know of, because I wasn't in the car and the tuner never mentioned it, so the computer shouldn't have been pulling timing tming correct? Well now it's back on with the same code so I am thnk that I replaced the wrong side. It said bank two but I am betting the wire that it thinks is bank two is going to bank one.

It showed 0 KR on the dyno pulls. Tried from 12.2:1 AFR to 13.1:1. Timing sweeps from 22 at torque peak to 24 at hp peak all the way to 26-29 showing a good bit of a gain. Then another degree on top of that netting zero found the happy spot. Ended up at 26-29 for timing and 12.6:1 AFR at torque peak and 12.9:1 at hp peak.

Same with the maf unplugged as I SD tuned it as well. Idles at 800rpm with 50kpa. I would say it is a well rounded tune that I spent about 4-5 hours on. ls7 show about 435 to the tires here. Dave's stock auto LS1 GTO made 298rwhp here and trapped 106@4000lbs. Have had full weight F-bodies trap 115 with 400rwhp.

TJ I didn't know you guys were a sponsor here!

I would definitely agree that it is an amazing tune and there was a DRAMATIC difference between the time I got there and the time I left. The car was smooth and pulled like crazy compared to me not being able to do anything below 2000 rpms when I got there. I am by no means saying that you did something wrong at all. I can vouch that he did everything he could to get more power out of it and I definitely got my money's worth. You were willing to practically bend over backwards until I was happy and I will definitely be back up there soon with the new intake and exhaust setup.

I was just wondering if anyone could see anything in my setup that is preventing me from getting a little bit closer to that 475rwhp. It may just come down to it that I just need to step up to better header and y/x setup.

Right on, I was just throwing in a statement about how out dyno reads a touch low. I agree there is a good amount of power to be found in the combo though.

At least you have a good SD tune as a base so when you do a intake don't be afraid to throw the maf in the garbage and never look back lol.

Fbody full weight with stereo and bottle of nitrous; dynojet 404rwhp and I trap 116+ with a looser 2.1 60ft ...every dyno is different from a place to another and from a car to another..

You have a beast with 435rwhp with stock heads and intake!!
