can i use an other MAF on TPI?
i am curious if i can use a stock GM maf to remplace the small tpi maf.
I am using a LT1 with all the tpi sensors, distributor etc..can i use lt1 3.5'' or 3.0'' lt1 maf on tpi harness?

Its possible to use an LT1 MAF only if you have a frequency to voltage converter and recalibrate the prom for the new MAF.
The LT1 MAF has a ~2500-12000 Hz frequency based signal thats proportional to the airflow into the sensor.
The ECM (if its using the $6E cal.) can be made to read higher airflows above 255 g/sec as well, but this takes a little work: need to source the F/V converter and recalibrate and rescale all the MAF tables using the injector constant to "trick" the ECM into seeing more flow.
