Engine/Transmission (1998.5 - 2002) Questions?

[SMason]

I have an '01 with edge juice, fass 150, ats exhaust three piece, 4 in turbo back, afe... At a stop I start to spool up my turbo, and get on the throttle after x amount of boost is built up. My truck pretty much acts like it has no fuel, it will stutter like I am rodding the throttle full/none... My question is, does it do this because my injection pump is going bad? My stock injectors will not keep up with the amount of fuel needed for those parameters? Or is the fass fuel pump not supplying enough fuel. The higher the stage the worse it is. It also does the same thing in stock, but not nearly as noticable. fuel pressure never drops below 9psi. It only does this when I build boost before take off. If I just stomp on it without building boost, can't even notice. I have really been thinking it is just the stock injectors.

Another question I do want to get upgrade injectors and want the mach 4's. Is this too much with stock turbo? In the future I am planning on twins. Would it be best to wait for that big of injector until bigger turbo? If they would be too big, which ones would be best?



If anyone could help please. I would love to hear comments

Welcome to torqe managment a coupl years of the 24 v have it yours does like mine you need a smarty or bd rad box . This way you can launch at big boost but if your trans is stock i would watch big boost launches

Sounds like you have a nice setup going on that truck. If you plan on injectors... . you better start by upgrading the clutch or automatic transmission before adding anything more than you already have. The Mach 4's are good injectors. A Super Stock 62 turbo from High Tech Turbo is a perfect match for 150hp injectors.

Second that You need some drivetrain upgrades to be launching like that. Only a matter of time especially on an auto. M-4's will be too much for the stock charger. A 62 be it II or HTT is a great combo with these sticks. Yes a smarty will help with that torque management:-laf

Ya I have been looking at transmission's full billet more then likely. I have been looking at the smarty and I will get that here really soon. Do you think that it will solve the no fuel problem... If so that would be great.

Thanx for the info guys I really appreciate it.

Yea, the smarty will take out the torque managment for ya.
