Default Anyone else thing my times are way slow.

Car is a 99 a4 z. Vigilante 4000 stall, tsp 1 7/8 headers, flow master merge , 4" cutout, ls6 intake, 3.42 gear. 275 50 15 et street. Back seats removed, free ram air. Not much else I don't think. Car cuts 1.68-1.70 60' every time. With a 28" tire it went 8.37 in the 1/8th and 12.97 @ 104 1/4 mile. Put the 26" back on it, went 8.00@85 in the 1/8th last week. No idea what tune it has. Don't know ow much a tune will add, but sent it to frost just to double check. 8.0 is what I see cars on street tires and stock stall run, just seems slow to me. Opinions?

It's not horrible, but it's slower than it should be. If the tune hasn't be touched since the converter, I'd say you'll get at least a few tenths just from changing shift points and removing torque management.

I know the car previously had a big cube motor in it. And than the stock one was installed and sold so I bought it headers only. Tune unknown and I just went ahead and put my stall in and never Messed with the tune

Yes i would say it needs a tune but if your going to do H/C/I i would just wait.

Car is getting a complete drivetrain swap this winter. Putting all this in my other 99 roller so the tune can just go in that car

given that 1/8 trap i'd say you're looking at what 107ish in the 1/4? seems sluggish, most likely because of the tune. no wideband on the car or anything?

fwiw my 3650rw bolt-on car went 12.2s on a high 1.6x 60' at irp. da around 2000' or so.

i'd say it seems slow, but nothing to get terribly worried about until the tune can be verified.

Well duh. That's common sense. If it was tuned for a big motor then it probably had fuel mods thus making it run super rich

Well duh, actually super lean. If it was tuned for bigger injectors and it had stock in it. Like I said I would've assumed the tune was changed
