2500 is not higher than stock. Stock converters will stall to 3000 rpm, and I know yours does since I did all the work to it. Im sure you are getting this info from ZZPs site, their "2500" converter is said to stall slightly higher than stock, it does NOT say that it stalls at 2500 rpm. It is just the model converter and not a true number. Look on their info or tech page, Zooomer himself said the numbers dont really mean anything on the converters they sell - see here ZZ Performance
As I have told you before going any higher in stall rpm is just going to make tire spin worse. Practice more on your launch, you have to be able to launch the car without tire spin and a higher stall speed just makes it worse. My Cutlass stalls at 2300 rpm and pulls 1.6 60' times and lifts the left front wheel a few inches, well did with 3.73 gears but I now have 3.23 gearing and still get high 1.6-low 1.7 60' times with this converter but I have a 3200 converter for it when I put the new engine in. Granted it is a RWD car I can go WOT from a stop and I can use a looser converter to launch the car harder, you wont be able to do that with a fwd car unless it has slicks on it and even then its a coin toss if it will spin or not. I know where you are going with this and FWD cars just dont launch on the street without good tires and lots of skill and practice otherwise you blow the tires and get smeared from a light! If you want to kill people off the line buy a rwd car and then its easy

ok, if i read it correctly so you saying going to higher stall speed converter is a waste of money if you going to be using on the street? what about as far as increasing hp and longivity life of the converter as zzp said, is that true? sometime when i do get a good launch,lol i feel like something holding the car back like it's not getting out of the pocket fast enuff even after the car is hook and i wasn't even spinning the tires that much. if you remembered i told you awhile back with the LS2 gto i raced both of the races were at a stop btw. first race he spun out and i beat him. the second race we both spun out, but his tires spun out more than mine cause i was half a car ahead of him. he end up beating me on fourth gear. i think the second race i should of beat him, but like i said it seem like my car seem to fall flat on it's face even after a decent launch. do you think it's the tq converter issue?

Your torque converter is fine and not costing you power. As soon as you are over roughly the stall speed the converter it is up to the output of the engine to pull the car. If the converter was bad your trans would be shot as it creates a huge amount of debris and will destroy a trans in a hurry. It will also make a lot of noise. Your converter is working fine. A looser converter will NOT give you more HP no matter how you slice it and many times will lower your upper rpm HP because it will be looser across the board. A looser converter is only going to make the car quicker from a stop IF you have good traction-Lower ET, but it wont make a car faster-higher mph on the top end unless the converter to start with was not very efficient. Once you go IC and drop pulley size the car will definately have more power all over and you will feel differently
