Transmission Problems?

[lakingslayer]

I don't think his trans will hold up to a 65hp tune towing heavy after he's limped it multiple times.

Like Kennedy said TQ is the monster here. Maybe we should start talking in terms of TQ vs HP when it comes to the trans.

I and several other people I know have towed with the 65 all day long. On a 65 tune my truck dynoed the numbers in my sig.

I think its a good all around power level. The problem comes in when you have a high mileage abused tranny that may already be in a weaker state. My truck was BN when I started bumping up the power and it has been fine.

You are being very careful with those numbers.
I tow 10,000# on the 90 hp setting and drive with 110 or 135 (Dyno`ed closer to 130, and 150!) and after nearly 80,000 miles, it is still holding together. I can run the pi$$ out of it all day long on the 110, and it will not limp. (No two trucks will act the same, but any LB7 should easily handle 100+ on a stock tranny!) You may not get all the power to the ground like you would with a built tranny, but it should last for a long time.

It's not the HP it's the TQ down low. You just don't have it or you'd be limping it...

65 is absolutely perfect for all around towing, power and economy. The 100 is right on the edge of limping under hard low speed loads. I have a 100 in right now and limped it once in the last 1200 miles. Its been good even under some hard loads so far. I am not too concerned since I am putting in a beefed up tranny in a couple months.

The 100 feels real good!

The 200 feels better!

do you wanna send me that 200hp tune??

Dude, quit begging and make your own. Start logging and start playing with the fueling and timing, and you'll come up with something that you made yourself.

You might have been better off with a Predator or a VA box or something.

well maybe if some of the people that knew what they were doing would answer my questions...maybe i could play somemore....but until then i'm stuck!!

You mean this question?

Which table would I modify if the barometric pressure were at 11.6? How would i modify the table just increase it across the board or just in certain RPM's? How high can i go on the #'s?

Use the logging feature on the scan tool and do minor adjustments to your tuning file. You can see what your boost is by the log and find out which table your truck is running on. If you want to play with boost I highly suggest a real mechanical boost guage and not the Attitude monitor. Don't go any higher than 29psi.

Waldoch, play with B0720, B0721, The timing tables, B1101, and the rev limiter. You don't need to play with the boost at all to make 100hp more than stock.

Boost will just clean it up a bit and help lower EGT's but isn't completely necessary. Predator 2.0 doesn't change boost at all in their tunes. They did exactly what Wasted said.
