I put down 357 with tvs and 1.26g/cyl

I don't think you are gonna find your missing hp in your maf!

After checking your log file i would work on your timing table and wrap it out to 7500, the tvs will keep making power if tuned right.

Too bad you didn't have a lil more fueling left.

you are correct. Check it out this is a comparison of my cylinder air mass and the cylinder air mass that it should look more like.

My timing table

What it should look like.

I'm not sure it's supposed to creep up like that. Mine flatlines at about 3500, like yours does, but it stays at 1.20, +/- 1 cell.

But forcerius, fix your fueling already.

Go turbo it's more fun I wish I was running e85 it would be fun too see how much power I would pick up. I'm too scared to run more then 16* on pump gas with the stock motor

g/cyl means dick. as long as your car runs what afr you want with the maf and pe combined. **** it. it will not effect power.

i run around 1.04 g/cyl on a 2.6 ring with the tvs. maf thinks it's moving only 24lb/min still cranks out 375 whp daily. the sooner you concentrate on power, and give up perfection, the happier you will be.

more to tuning than AFR and timing.



Not bad numbers though. However, I got that on the 3.1 pulley....

11.2 AFR, 20* of timing and a hot/humid day.

My torque wasn't that though. Hit 256 on the highest run for the tq.

Area maybe you can point me in the right direction I posted my tune. What do you think I can do to it to get more hp besides changing the stoich cause I already changed that in my new tune. Also what a/f is everyone running on e85.

Im running 12.0 until 4500rpms then 11.7 until redline. When you change stoich to 9.7 hopefully you dont have idle issues like I did. My idle would get high, around 1100 rpms then would go really lean and want to die. I am going to try messing with my idle overspeed timing to see if I can get it under control

Yeah right now my idle is fine and doesn't go lean it sits right at 14.7 for the most part. I am not going to tune my car with my wideband reading 14.7 though. I am going to program my lc1 to read for e85 I am praying when I do that and get my rsfs I can pull at least 345hp.I need to check my sc and map and make sure its sitting right since the dual pass install.

Hey quick question. I installed dual pass option b with a new intake mani gasket. Could I be loosing boost from the sc or manifold not bolted down all the way? I am seeing 20 psi with a 2.8 pulley and 3in exhaust. I am just trying to narrow down the problems and why I only made 305.
