Default In the 12's now with ls6 conversion

I have an 02 trans am with ws6 hood and lower air box, lid, P/P/T/B(with bypass) A.I.R. delete, 243 heads, 02 z06 cam pacesetter LT and ORY, flowmaster catback, panhard bar kyb agx rear shocks(only suspension upgrades) crap tires and a frost tune.

the first week out my best e/t was 12.89 best trap was 111,
this past friday was a lil bit better. I did take my carpet out to clean it so i said what the hell let me go run it, I had to let it dry any way. Other than that I have not had the back seat in for a wile and I take my spare and jack out when I go to the track. My best this past friday was 12.79@109.50 D/A 1325
60 2.075
330 5.534
1/8 8.323@88.57
1/4 12.797@109.5
My 1/4 trap seems low to me on average i only gain 21-22mph on the big end.
Yes a stall is in my future.

Crap tires, I don't spin much but I am soft out of the hole so I don't spin.
With my tires the best 60 I have had was a 1.9 so ill sort that out on down the road.

yea ill be saving up over the winter for some suspension. Spring...tires, stall, and hopefully a 12 or 9" by the end of next summer. Cam... I dunno I might go turbo one day might not, not sure yet. I need to make up my mind first, that is why I am not going to be putting a stall in till next year.

I don't know how the ls6 conversion you have would compare to a crate ls6 like I have (#'s in the sig). I would think the tune is way off or something is wrong. My bolt-on ls1 went better than your ls6 conv. Funny part is the stock tune should be pretty close to a ls6....atleast mine was.

You would think it would not be much different if any at all. I have checked every thing and the mech end is fine

Get rid of the flowmaster for starters. Mine really liked it when I went to a single 6" round dynomax 3.5" muffler over the optional slp SS exhaust.

i'd be looking for 115 at least.

for comparison sake, my lid/muffler m6 car went 8.29 @ 88 with a da of 2250'. granted, that is not the norm et for a stockish m6 car, the trap is close to what others do. it's a 99 car on stock everything; clutch, slave, master, intake, tb, etc etc etc. literally 2 mods. i'd be straight up pissed if i did all that work and gained 1 mph in the 1/8 and nothing in the 1/4...

How inaccurate is the factory tach? It shows It shifting at 6100, but its suppose to be 65, speedo off a bit as well. I gained
4-5mph from this conversion.

Shoot me an email with your full name so that I can look up your file. If the car is shifting at 6100, that's where the MPH is being lost, or quite a chunk of it.
