TST R47 in

Note - Make sure to do this with plenty of day light, the cam sensor in the dark isn't fun at all :-laf



Anyway, pulling a load is greatly improved. I pulled 32k out to the Tulare Farm Show averaging around 9. 5mpg on a combo of 1/1 2/1 2/2



Ran around in 3/3 while in town and enjoyed it. Temps were controllable, with a few mild spikes on settings of 5+ even with the EGT's set at 1420 and boost limit at off. I'm curious what kind of PSI I'm actually hitting since the MAP sensor is limited to 40psi.



The twins program, IMHO is a must. Mine is the 24psi twins, so it isn't violent, but does come on strong.



I did notice a bit of shuttering (rails running dry??) on level 6, backed off right away. I still need to get the FASS on, so that could be a big part of that.



The southbend CON FE is great! But it does seem to have a difficult time engaging from a stop into gear, which can be frustrating, any thoughts?

MY FE is like that too, but it is getting better with some miles. Do you have a fuel pressure gauge? I do and I saw my fuel pressure drop to 0 on level 5/WOT, You need a FASS or some other fuel pump. I am running a Holley Blue in series with the stock LP and can't get below 15 psi on Lvl 9/WOT. but I am now running out of rail pressure with my TST VA C3. 1 stack. You are probably running out of rail press. also since you have injectors. I make more power (58hp) on lvl 5 than I do on 9 with the VA @ 100%

Are you running your stock fuel lines with the holley? That was the way I thought about going and it sounds like it does pretty good. May ebay the fass



No FP gauge, I need to get one on as well as a boost gauge to know what I am actually hitting. 40psi comes very quickly.
