Message: [QUOTE="lincolnlocker, post: 1425559, member: 944"] that proves my point as to you wanting more then the 38r could or should do.. yes you can pull fuel but you want what your setup can and will do from max effort. so yes, switching to a turbo that out performs a 38r is the only way you are going to do that.. that is just common sense.. I however leave my dually in one tune for everything I do with that.. and that is the hottest tune that makes over 450hp wot.. and as I have stated before, tow whatever I wanted whenever I wanted and never had an issue.. but it is also maxed out with the measly little injectors that are live tuned to the setup.. do I have lower tunes? yes.. do I use them, no! I don't need to because everything works as it should.. with an injector swap, I will be turbo limited then.. but as mentioned, a few people with the right gate setup have hit 600 with a 38r.. at that point I will not be able to tow with the all out tune. that is just common sense.. I will need a different tune other then a pulling tune to even drive it on the street.. for the record, I'm not arguing that the sxe isn't a better turbo.. it very well should be because it is designed to be and flows more air.. with the right tuning, without trying to make gobs of power and still be able to tow then the 38r and any injector combo like tarm mentioned, can be tuned accordingly but you wont be able to tow without switching tunes.. that is obviously not possible. the sxe or whatever that is designed to perform and out flow the 38r will be the cure all to that.. it should be.. plain and simple. but nobody can say that a 38r is complete junk cuz it wouldn't work as long as tuning is on point with its setup or has a lower tune that is designed for it.. again, I think is what is happening is that people wanted to tow in a tune that makes over 500 hp and a 38r isn't happy there so that is when the turbo got swapped out.. yes, that is a cure.. duh.. it very well should be. a 38r out flows a stock charger by quite a bit.. guys tune their trucks and now the stock charger is junk and swap to a 38r... bam! it's cured again.. same thing with reaching the limits of a 38r and after market injectors.. swap to a better flowing turbo, bam! it's cured again.. put bigger injectors in and bam, back to square one.. its a never ending cycle.. bottom line is a 38r can be tuned to run cool with any size injector. it may only be a 300hp tune but it can be done.. if not then there is something wrong somewhere else.. period.. tarn nailed it when he said the turbo itself could have been a bad run off the line.. if so, very sucky.. if not, something was wrong.. as for the guys wanting to tow with over 450-500hp, obviously the 38r is past its limit.. back the tune down and run it or just get a better flowing turbo.. obviously that is what a few have done.. good for you. but you can't say the 38r is junk just because you are trying to do something with it that it isn't designed to do unless in fact it was junk from garret... live life full throttle god bless america and the farmer who feeds your fat ass [/QUOTE]
