Didn't exactly know where to put this... I have searched and searched but do not have an exact answer.
Q: is there a gm 2 bar map sensor that fits the non threaded hole in the back of the Holley intake. My stock lq9 sensor is loose. I understand that the cobalt sensor will work for the 2bar range and like that it's "drop in" but will that sensor fit snug is my question. Thanks

Not sure if there is a bolt hole there to hold the sensor in or not, but what I did is tap it for 1/4" npt (or 1/8" cant remember) and put in a hose barb and ran a hose to the map sensor. Works just fine.

Atomic, is that your IAT sensor in the back too?

Here's some info regarding N/A vs FI MAP Sensors for the hi-ram. http://documents.holley.com/199r10572rev6.pdf

Yep, I drilled and taped a hole for it back there. Worked better than the intake pipe where it got soaked with meth.

Did you have any problems with hot restarts due to sensor heat soak?

My truck will fire right up when cold, but when it gets hot it takes a while of cranking for it to fire up. I'm thinking this is all due to heat soak since it seemed to get better when playing with the charge bias.

I have my iat sensor screwed into my intake like atomics and I don't have any issues with hot restarts or heat soak in the sensor.
