Stacked EZ with my TST PMCR

[JCarroll]

Just finished stacking the Edge EZ with my TST PMCR today and WOW! what a difference. I talked to lots of folks who told me it would help but I had no idea how linear the power curve would be. Pulls like crazy smoothly to redline. I have the Edge on setting# 3 as reccomended and the TST on 5 pwr. and 8 tq. With the water and meth. turned on I had enough power to lightly slip my new cerametallic clutch slightly on top end.

I plugged the Edge into the MAF first, then the TST into it. My TST remote now shows a max. boost pressure of 19 psi. which is the Edge boost fooler I'm sure. My gauge reads 35 psi max. Has anyone tried plugging the TST in first then the Edge into that? If so let me know. What max boost would be recommended with the stock turbo? I know it has a short life span but hey, I'm just playing. Any success with new injectors. Any input would be appreciated.

I wouldnt go over 33-35 lbs with a stock turbo.

You did it wrong, the TST goes in first.

Just like Justin said, TST 1st since the TST does the majority of the fueling, especially past 19 lbs of boost.

Error Codes

When I switched and installed the TST first in the MAP Then the Edge I cranked the truck and drove down the road at WOT I had an engine code come up. Looks to me the only difference would be the Edge telling the TST that max. boost is 19 psi which I'm sure is max. fueling level for the TST reading the MAP sensor anyhow. Power seemed smoother and more linear with the edge plugged in first. Anyone else have an opinion?

No codes here.

Thats weird, I have done TST first and know of many others that have done it that way without any problems.

I tried an experiment tonight. I had the EZ hooked up first then the TST. I set the truck at nearly full power 7hp-9tq. with Meth. /water injection activated. Truck pulled hard but no clutch slipping. I reversed the hookup with the TST first and had TST turned all the way down to 3HP-5 tq. and it would slip the clutch. Lots more power with the TST box plugged in first. Clutch slipping is a whole different beast. New disc going in Fri.
