pyro problem?

[blackbear]

greetings hellas. i have a 94idit that ive recently swapped out the old mechanical isspro gauges for new isspro electrical gauges(evII). the former owner installed the pyro after the turbo, so i mounted the new one in the drivers side manifold. which is located more towards the second to last cylinder. i did notice about a one inch crack in the manifold too. i didnt use the added wiring for the pyro since i didnt need the extra length and the instructions stated it was not necessary to do so. i linked the power and ground supply separately than the other gauges. so after running the truck it seems to me the pyro lags quite a bit. i havent removed the old thermocouple yet so i reconnected the gauge to compare the two. they both seem to run at the same temps?? idle is close to 250-300*, 55-70mph is running mid 400*s. starting at a full stop and using heavy throttle the post pyro climbs faster and higher than the pre turbo (pre turbo reaching 450*ish and post turbo around 600*). the truck has an inner cooler and ats elbow and dp. do i have a faulty pyro/thermocouple? any help is appreciated! thanks.

Sounds like it might be a bad thermocouple.

BTW, that is sick looking truck you have. Any more pics you could post up?

Thermocouple, that seems like it right. Ill call isspro tomorrow and see what they say. As far as the gauge starting at 100* instead of 0*, I couldnt say. The gauge I have numerically starts at 100*. Thanks for the compliment '94IDITurbo7.3, I'll have to make time to wash it before I make time for photos.
