Im thinking of changing to 3.73 gears in my auto camaro and i have a handheld tuner i have been using to tweak my tune because it was free and it has a gear change option so will that be alright until i get a dynotune ?

also with a full bolt on, geared car how much ET will i loose from a good dynotune from texas speed ? how much horsepower will increase ?

yes.


maybe you will gain 20 rwhp and knock 0.5 to 0.6 second off of the ET and increase ET mph by 3-4 mph.

not trying to throw the BS flag but theres no way id get -.5 of the ET from a tune...when i get my 3.73s and UD pully ill be knocking on 11s door with a stock stall so ur tellin me with a tune id run 11.5 ? no way man lol...maybe -2tenths 20hp at the MOST ...

Yeah 20hp at the wheels u will only knock bout 2 tenths off.

i said 0.5 to 0.6 sec and 3 to 4 mph becuase of the 20 rwhp gain and 3.73 gears because these gears multiply torque? if you get a stall speed converter how much you will ET? i assume with your mods you will ET 12.9@~107 mph or so with good 60ft.

so ur saying with my mods i will get a 12.9....i ran a 12.6 before my ls6 intake and ramair, since then i have also fixed my sluggish 2-3 shift problem and have taken about 100 lbs out also....with an underdrive pully and some 3.73s im gonna be knockin on 11s door man.

Uh....no.
Depending what his gear ratio is to start with he will most likely see at most a .2-.3 reduction IF he adds some good sticky tires.
There are ton's of threads on this subject.

I have a full bolt on formula stock gears without a stall.I run 12.6 at 110mph also.Honestly I don't see u in the 11's,but I'm guessing 12.2 with a tune and 3.73 gears.

looks like our cars run the same time almost....i ran 12.6 -ls6intake, ud pully, ram air....iv got faith in stock stalled 11s

LS1 bird

Yeah but I can't wait till I get my FTI stall.I saw full bolt on ss running 12.0 all night and one pass at 11.8.I think we have reached our stock stall limit.If I were u i would worry about getting the stall before the gears and then gears later.

yeah but i can do a gear swap for like 250 bucks because i know people and a stall is 720 plus an 1100 dollar tranny build and a 400 dollar tune, i just cant afford it and i want 11s...i have a feeling i can get some nice 11 second passes with my stock stall, then ill put an ss4000 with a built tranny and a tune and see what she does next year.

LS1 bird

Yeah I hear ya on that one.I'm getting everything done 4 like 1000.00.Let me know wat it runs wen u get everything done.I would really like 2 know.It will be close to the 11's.Best of luck.
