Well what I really like about the Smarty is the low end torque they add. Right now I made 411 hp with my current setup. I'd like to be in the 500 hp area with EGTs under control. Trying to weight the advantages of the SE single vs twins.

This makes me wonder why I can still hit 1550* with my 62/s475 setup

add more fuel you don't have enough. I ran 200's with same turbo at first and they worked well low egt's even the 240's were decent egt's. I don't think 150's are near enough fuel because the work pretty well with a single 62.

I wouldn't think going with a bigger injector would drop my egts by like 300 degrees haha. I was thinking water meth

you would be surprised how warm under fueled truck will be just like an over fueled truck. I had ddp 200 240's and lightning III's with this turbo setup and could drive them all around town etc. with the 200's I don't think going down the track it went over 1300 with 240's would hit 1400 and the l3's were a little too much fuel. 575hp 603hp and 683hp all on same dyno

It's not only even at WOT that it bothers me. In overdrive 65 mph up slight hills on the highway no load I have to keep it very light on the foot or it breaks 1000* just cruising. Passing people on the highway not even hard on the throttle I can get 1200 very easily. Otherwise flat ground 65-70 mph cruising runs 750-800

Ever think about getting a 3 piece manifold?

Yeah. I'm running the stock manifold with my compounds. I would hate to rip all that back out to put a 3 piece manifold on. I hear they don't matter much anyway. I may just do water meth. I'm a dealer for snow, so 500 bucks and it's fixed for sure

whats your rpm at when your doing this? Sounds to me like large exhaust housing on your turbo or turbos. it's not spooling I went from a 1.32 to a 1.10 on my 475 and that made daily driving nice and I lost nothing for power
