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 |
Normal for a bolt on car in my neck of the woods. |
what was DA during your runs? my 98 a4 2.73 with 3200 stall goes 8.2, only mod is stall and K&N but its tuned. |
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. |
My average d/a is about 5000 so that time would be great where im at! Just depends where your at |
Indy area, talked to frost today, injector tables were set for 36lb and he said the tune was way out |
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 |
