I almost went with a TH400 but I just know I am unwilling to compromise on over drive.
thanks man,yea its an s475,just picked it up off ebay was like 650-700 bucks,yea the only reason i went with the 400 was that i had one laying in the shop and my pops knows them pretty well so we put a tci kit in it.iam trying to upload a video of the thing running off of my phone but it wont work,POS phone.

My siemens deka 80's have the ev6 connecter. I bought pigtails and soldered them onto my harness, or just buy the adapter. You can buy drop in injectors for the truck harness but they are pricey . I would also go ahead and run a walbro 450 as youll be pushing the limits of the 255 on 10psi with that beast of a turbo. Later on add the 255 on a hobbs switch when 12-15psi gets boring. Awesome build by the way!!!

Good job bro. I thought I read somewhere that the BOV goes ahead of the MAF.

i was wondering what people were doing with the placement, i thought i asked on here when i was doing all the piping and no one had any input so i put it there. either way can be moved easily. And thanks i cant wait to start driving it with boost... i drove it around the block a few times with no boost just engine and its no slouch compared to the old oil eating blubbering 383 that was in it. haha. hopefully will be putting some smoky burnout videos on here this week.

So i removed the BOV from where it was and put it closer to the charger. i made a few minor changes to the truck in the last week or two. i got a tune from black bear and started running it and found that when boost started to build it would go lean, hooked manual guage to the FPR and found my pump is shitting the bed. so i was curious as to what guys are running for pumps with this setup? i would like to keep it a single inline pump.... any input would be helpful.
