Am I expecting too much?

[96whitesvt]

I have a 2011 Gt 6A with Boss IM, Airaid, Off-road X pipe, axle back, Shaftmaster D/S and 4:10s.
I have a custom tune and on bigs and littles the car ran 12.1@114 with a 1.9 60ft at 2100 DA. I really believe the car should be quicker or is that all it has. With VMP tune and 4:10s only with the bigs and littles it went 12.2@112. I just figured it would pick up more with all the new mods. Any suggestion or opinion is greatly appreciated.

What was the DA when you went 12.2? What is your car shifting at? With the boss manifold it needs to be shifted higher.

with the 4.10s your shifting into 5th before the trap even with the boss mani?

OP is an A6.


OP, get a converter in it.

Gears may be killing you. On my friend robs car we expiramented with gears and got the best results with 3.55s.

The car is shifting around 7700-7800 rpm. I thought about the converter but really, the mph is what I think seems low. I have thought about going to 3:73 or 3:55. I figured that would make the 60ft that much worse. The DA Before mods was around 1800. I just figured it would pick up more than 2 mph with the intake, CAI, off road x and D/S.

Converter+3.31's+Better tune= better ET and MPH

I just downloaded a new tune in it tonight. Now to make it to the track to see if there is any difference. Just kinda bummed that it 60 ft was better stock lol. Now to see if I want to put converter/ gears in it.

 

[Blazer707@TBR]

You should at least be around 1.8x 60 ft with stock converter and big and littles.

 

[96whitesvt]

It did when it was stock and with the VMP tune and 4:10s. Now best is 1.93-97, no spinning.

your right, my bad, I read right past that.

I agree with what was said, if you wanna crush it N/A with the A6, get a good stall convertor and drop that gearing back down to 3.31

the 4.10 in the auto are just too much. While you can run them, they do more harm than good it seems.

 

[96whitesvt]

I also occasionally spray the car. It seems to
Like the 4:10s, but I could be wrong.

I havent been back to the track yet but my car loves the 4.10's and the converter, just not sure if itll like them with the gas turned on

 

[96whitesvt]

What converter?

 

[N20JUNKY]

What converter?

I have a circle d 5c in it now, ill be pulling soon to restall it to a 2c since im more focused on running the best on the gas

 

[96whitesvt]

Half tempted to put the stock intake back on.

:burnout: thats whats on mine now, it has never pulled as hard as it does with the 4.10's, converter, and stock intake

 

[96whitesvt]

Well I will give the new tune a try. If it runs the same or close, I'm gonna take it off. It will 60 ft a lil better and I don't have to turn so many rpms. Plus part of that money can go towards a converter.

What's your car run?

 

[N20JUNKY]

With the boss intake, a 3.73 gear and the converter it ran a 7.30 @ 96 short shifting at 7200. Haven't ran it since the manifold and gear swap, but I also changed from cj springs to k springs and sold my front welds so I expect to slow down a few tenths
