[QUOTE="INFRNL, post: 1534944, member: 9835"] At what elevation are you considering high? I'd also like to see results of the 366 in comparison. I'm currently in the process of trying to figure out what the best setup for me is. I'm also not sure that i chose the best injector size. I have recently read so many mixed results/opinions on injectors. I have an 03 cc dually with 4:10s and 35's. Back in 2012-2013 iirc, i talked to Bill (PHP) and decided on 250/100 injectors as that would be the limit for my pmr's. I tow occasionally pulling up to 15k. At the time I chose to get a t4 setup and run the pius lasb turbo. Does good but imo too laggy here at 6500' in elevation. Fun when empty and you learn to either spool up (which I don't like to do) or you have to ease into it off the line (not ideal either). Recently i upgraded to a hydra chip (didn't exist back then). After talking to Dusty (1023), i decided to get a 369sxe w/.91ar housing (for better spool up at my elevation). Slightly more lag than the lasb but moves a little more air. Can be fun when timing is perfect after easing into it from a dead stop. Punching it off the line is not a good option as you sit and wait for the turbo to spool and fill the road up with enough smoke causing someone to call the fire dept(actually happened once just outside of town) To me, the 369sxe likes to be around 2000-2200 rpms . If rpms get around 1500 give or take a few, and you need to build speed back up...it will put out a lot of smoke until 1800+ rpms. I know the 35's don't help, but stock tires don't help much either. I'm currently working on a 76 f350 crewcab getting a 2001 factory forged motor with a zf6 and 250/100's. Irate recommended the 366sxe w/.91ar housing as it should help spool up better. I don't know if I chose the right size injectors (I've lost 1-2 mpg)but i wanted the power for fun with occasional towing. Also don't know if I made the right choice for turbo. I definitely have to watch my egt's empty and towing) higher elevations make it even worse. The best my truck has ever done in regards to fuel economy and egt's was stock injectors and piping, turbonetics turbo and php tunes. I had zero lag, truck just took off like a bat out of hell and best fuel economy this truck has ever seen (14-15 in town, 17-18 hwy...hand calculated) not too bad for a big cc lb 4wd dually in a hilly 6500' town. Now i have to fight to get 13...winter fuel gets me down to 10-11mpg and i drive like an old man. Thanks for listening to me ramble [/QUOTE]
