Some of the LBZ have EGR issues it could be that. Does it feel as if its down on power any? If you drive around a bit and are easy on the throttle the soot will build up in the exhaust. Then if you get on it it will smoke a bit more then normal. A 70 HP tune is a bit much on the LBZ with a stock tranny especially while towing.

Should i change the programmer and put it to 50 horse. Also i don't know much about tranny's but my temp running loaded never gets over 200 degrees. If the tranny was working extra had would'nt the temp go up also. Just wondering. Still the same as befor, but she does lay down some serious smoke when i'm on it! Can't she anything behind me. 2500 you said to put back in the ac delco filter. Is the k&n not worth a crap. any help to get back mpg that is money in the hip pocket in my job.

since u have a lbz, u can do the airbox mod and leave the stock filter in there, there better, The stock set up when properly modifies of more then capable of giving the cleanest 500hp worth of air.

IIRC correctly the trans temp should be roughly ambient temp + 100. If you're in that range you're OK. If yours is running cooler than that's a good thing.
What are you reading for boost numbers?
