do I need to change out the torque converter?

I have done a lot of reading and with my set up i know ive done something with the hp on internal parts I dont have ac0cess to a dyno so I dont know how much. I am running a spartan 250ll right now but was on the 300el and it felt slippy when i hammered it.
My question is should I be looking at getting a better torque converter in it to run the 300 and 310.the 350 is off limits til i do but any sugestions?

Monitor your tc slippage with the tc locked at WOT.. You don't want it over 10ish

0-10 RPM is error.

Anything above that I'm not even sure at this point. Both my SunCoast converter and RCD converter would see over 10 RPM with the converter locked. Cruising speed, it would always jump around below 10. WOT, I would see 40-50 RPM at times. Never saw the 200+ I started seeing with my stock converter though.

Yeah I knew it was just error readings in the signal but I thought on a stock convertor once it started getting actual slip readings above 10 that it would work it's way out.

Wasn't the case for me. Mine was still holding up when it would see 200+ at WOT.

I didnt notice much slippage at 310tune but with winter coming I turned it down to the 275 to stop the juppyness so I could keep it on the icy roads. now that its warmer I noticed it. I programmed it and took the tuner out before the wife saw how to program it.She swears that I did a wheelie in it)
I just read from Spartan that its good to reprogram a tune every once in awhile so I'm gonna reload the summer smoke tune, and have some tuner cars chase me....... I REALLY WANT TO TRY THE 350 TUNE!!!!! BAD BUT IM PRETTY SURE ILL NEED MORE THAN A TQ CONVERTER IF I TRY IT PREMATURELY
