i've decided not to drop pullies on my ss/sc, i plan to have my supra by next june.

BUT

i want a little bit more power while i still have it, is a tune worth it? right now with the weight reduction im running side by side with cars that trap at 102-103. is a tune worth it?

 

Wait you don't want to change to a smaller pulley but you will get a tune?

 

smaller pulley = fuel injectors, cooling mods etc etc. im saving for a supra all i want to spend on the ss/sc is another 300$. i was wondering if a tune was worth it with the mods i have right now

 

Not untill you get injectors.

 

not worth it. put that in savings for your new car.

 

i need injectors for a tune on a stock pulley cobalt?

i probably should but i want a little bit more out of the balt

 

You dont... but your not really gonna get too much out of it... But i guess there are minimal gains..

 

300$, best gains per $ what would you do?

 

If you dont mind getting used parts... you can get injectors for about 100.. and a pulley / hub kit for about 50-75... spend 125-150 on a tune and your at 300-325...

Really, thats the best bet... Changing the downpipe would benefit too if you havent already...

No need to change exhaust at all...

 

get a tune from a member on here. u can always do gm stg1 (injectors and tune)

 

there may be minimal but not worth the 300..

 

well i have problems with my exhaust, my current setup up is vortex header, 2.5 downpipe, and a baffled exhaust (1 inch exit) with cat. if i deleted the cat, increased all piping to 2.5 and the downpipe to 3 inch. sold my exhaust and buy a straight through 2.5 inch cat back what kind of gains would i see over the setup i have now?

 

u might get like 10whp gain for 300 tune...lol

 

You would see very minimal gains... not as much as you'd expect... what your doing is opening up the exhaust for more power later on...

I didnt pay 300 dollars for a tune.. lol...

 

ya 300 is nuts, I paid 50... i think.

 

Wiht hptuners you have to pay atleast 100... i overpaid 150 for my first tune.. my second tune cost me lunch.... and i personally like the guy way better.. lol..

 

Well my guy bought all 2006 cobalts VIN, so I got mine for 50. and if I need a retune I pay for his gas or something.

 

Yes yes...

I need hptuners myself lol..

 

so 100$ for 10 whp, thats not so bad, my rev limiter would be increased to 7000 also? or is that dangerous on stock pulleys

 

just get some 42's a pulley and a tune

 

42's 3.0 or 3.1... + street tune. how much extra trap mph would i see from that?

 

Not sure.. dependant on driver...

Uhhmm... with inj's.... tune and pulley.. about 25hp or 30 hp...

 

Not sure but it's deafinately seat of the pants. And it aint to bad on the pocket book

 

Well on that set up I ran a 14.0 at 104-105... I even had wheel hop.

 

42 pulley tune looks good right now. helld runs through the 1/4 at 104, lost by a car to 120 to him as my car is now, so that should equate to 106-107 mph, now i want to know about the car, whether i can get it to run that or not is a different story.

from what i can tell these mods would add up to 250$ which is great

and will my current exhaust setup effect a dropped pulley setup? rememer, stock piping2.5 dp and baffled exhaust
