Dyno and countless first had reviews state you are wrong. Peak might still be the same but takes much longer to get there.

I've found egts are a bit higher just cruising with my profab manifolds and up pipes vs the stock stuff. WOT i definitely a different story though. Bigger isnt always better for towing. Honestly for towing heavy the 3794 is probably about as big as you want to go to keep egts in control. Any bigger and the stock turbo is probably better. Twins would be best, but its alot of cash. Danville's 3794 has done well for me towing. I'll be honest though, power is up, and so are the egts a bit while towing. The stock turbo ran pretty dang cool for me towing here in MN. It barely ever broke 1100*. BUT, also had quite a bit less pulling power vs the 3794. My buddy has danvilles 4094 stg2r, and his truck runs warmer than mine towing, even though his spoolup from a stop is about twice as quick as mine.(4094 ex. housing is quite a bit bigger than the 3794)

I had Mark's stuff for a year or two and now am doing my own tuning. Marks stuff ran alot cooler than the PPEI stuff I tried originally. Marks tuning was alot more fun to drive than the PPEI tunes. That and Mark is a super nice guy. But, tuning only goes so far for spool up etc.

I personally would look at getting your turbo rebuild with a port and polish. Not sure what that's worth for EGT's exactly but if you're not really after more power no point in spending thousands when you can spend hundreds.

What all else is done in the motor? If your stock internally I'd be careful. I'm running everything you can do basically with stock turbo , injectors, and cp3 in my lmm and motor innards are stock. Got max effort tuning by ppei and I'm a turbo size bigger or injector size from popping my motor.

This with water/Meth or S475/stock. No need to build the trans unless you are going to race it...

So you think a stock trans will hold up towing with twin turbos and a tune? I wouldn't give too much advice......

I couldn't tow on a stock turbo without limping my Lilly, I could make my LMM converter cry the few times I actually towed.

I built my trans ASAP this go around, well, it came out real fast but it was sooner than later, lol.
