What mods next?

On my 97 I have done the gt38r with 1.0 housing, mbrp 3 inch downpipe into 4 inch exhaust with a resonator, 6637 intake, shimmed fpr, ts 6 position chip and a high frequency high voltage idm from swamps.
If i switch to the 140 horse tune I get alot of smoke and notice a fuel consumption increase but i expected it so i run the 75 horse tune most of the time daily driving and 50 horse tune when i tow.
I am thinking of going to an s&b intake over the 6637. I also have been looking into efuel conversions and a t500 hpop before looking at injectors, what is the most cost effective thing to do next? I also think I have an injector issue since I occasionally get alot of diesel smell at idle sometimes and a come and go miss/vibration while driving the truck has 186,000 miles on it and I put everything but the chip on at 178,000 the chip was at 184,000.

I noticed an increase in throttle response and quieter injectors from it, my original idm died and had to be replaced was the reason for going with the swamps and it was a decent improvement but not something I would say is a big bang for the buck just to buy as an upgrade.

nope 85 305 wrong again.

the gt38r is a Ball Bearing turbo, and it's a bolt-in upgrade for the Super Duty turbo....they will not fit the OBS without changing the :

drivers side exhaust manifold
both up-pipes
the pedestal
the turbo mount
the spyder
and the exhaust will have to be modified, as well as the intake plumbing....most just use the larger intake plenums....

why are not thinking of swapping intakes? i would do HPOP and e fuel before injectors. they will help out your current injectors and when you swap your new injectors will be happy and you will get the most out of them from the beginning. IC can be done before or after. i did mine at the same time

I am going to swap intakes from the 6637 to an s&b and the injectors are because I have one at least that is getting hung sometimes it will smoke at idle and smell diesel pretty bad
