Ok i know i probaly sound like a dumbass but i was talking to a few tuner shops none of them even had an answer for me tryed google and yahoo serch 1st then LS1 tech after that failed on me to. But down to the question i just added im guessing 10~15hp to my car and im getting exshust done at the end of the October the shop i talked to said just from the exshust i should gain 10~20hp but he could also for 200$ more tune my car to push out 50~65extra hp with the Xpipes im getting now to my question how much power can a stock 4L60e take? Im doing the exshust regardless its only gonna cost 800~1100 parts and labor. Pending if i do the dyno tune. Im just trying to make shure i dont blow my tranny out adding to much power.

I think GM says 370 ft lb of torque. I've been told that anything over 400rwhp puts you on borrowed time, although some have/are running well over that.

Sweet thanks dude i cant get on the GM website due to im still running internet trough my PS3 and a 32inch plasma screen tv lol so lets see.... maybe ill have 350~360hp and probaly 340~360TQ so my guess would be about 300rwtq afterwards 360 -23%loss from auto trans or at least thats how my friend told me to calculate it or maybe he said 30 not shure but o well lol so i should be good for a while before i got to soak time and money into that

ok performanceabuilttransmissions.com has trannys that would be perfect for my ultimite goal for 2,250 with a 2800~5000 stall converter also my rear end i can push 390tq to my 237 limited flip (stock) or so it said on google
