TST turbo cooldown issues

[SKneeland]

i noticed last night when i shut down my engine that my fuel pressure dropped to zero while the turbo timer feature on my TST kept the engine running for the desired time.



a: is this normal for the TST box?



b: will this be damaging to my cp3?

I'll reply with a guess since nobody else has... . when looking at the directions on my cool down harness, I remember them saying not to tap into certain fuses or the truck would run out fuel due to the fuel pump shutting down. I think it might have been #26 or #28 on the 2006 trucks.

its wired in exactly as per TSTs wiring instructions

and its a mechanical f. p. gauge too before anyone asks

I had the same problem on my 06... you need to call TST and get their kit which keeps the fuel pump running during cooldown. It fixed mine! (They tried to charge me $25 for the kit, but I refused because this should be included to work right!!)
