Your numbers suck, your A/F sucks even more. Time for a tune.

 

Your mom.. JK

What should I be seeing? My A/F was around 11. I plan on a tune as soon as I gat the cash.

 

You should be seeing 270-275RWHP, maybe a little more torque.

Your A/F looks like it's all over the place too.

 

I think your numbers are pretty good... Your AF ratio is very rich, you need to get a tune.... How do you like your aluminum flywheel? Does your motor rev up faster, did you get better aceleration? Do you have stock gears in the rear? Spec said with 4.10's theres no problem bogging, but with the stock gears you might have to slip the clutch a bit to get it going? What are your opinions?

 

Lightweight flywheel with stock gears would be a little harder to get it going, that's one advantage to a heavier flywheel, it'll be able to get the car moving quicker, but from a roll...you get the idea.

With 4.10 gears it'll be fine with a lightweight flywheel.

 

I do think the acel is quicker with the alum fly. I do have stock gears.

 

It def helps, but in a perfect world with 2 fully equal cars & drivers, the stock flywheel car would have a little advantage until you got going 60+.

If you were looking for 9's at the track, it'd be worth debating which is better.

 

Your numbers dont look to bad to me. You are running rich though.

 

yeah get a SCT or Diablo tune, lean it out to around 12.5 and you should see 10-15+ at the wheels. Tunes- when done by a good tuner are worth their weight in gold. I picked up 27 at the wheels in my mach 1.
