HP difference between 3.1s

[Hell_raiser]

hay are all 3.1 from 1990 till 96 the same is it just the computers that make them have different hp like a berreta has 135 hp and 185fb and a cutless has 140 hp and 185 fb also the sunbird has less power so is it the computers cuz my car has 135 hp 180 fb and lol i want the extra 5 hp/fb

94+ are 3100s so they are different. The gen 2 aluminum head 3.1 engine used in the grand prix, cutlass, beretta, cavalier, sunbird, etc are all identical. There are tuning differences but I don't know about them being 5hp. I get that out of the chip, but that is from changes I make, not changes GM made between platforms.

There is a certain year 3.1MPFI L body with supposedly 5-10 more hp than all the rest MPFI's. How true is it? I don't really know.

Not true

there were some code changes that gained 5 lbs of TQ but HP was 140 for all FWD 3.1's

94 3100s in Berettas had 160hp, whereas 95 and 96 Berettas only got 155hp.

That's odd.. Maybe the plastic valve covers added HP

so were the 94 ga's, skylarks...

i read a couple reason's.
one was the 94's only had map sensor's where's the 95 and up had maf and map.

also read that the 94 3100's had i guess a less restricted exhaust system.
where's 95 and up had a choking kind.

i can tell ya one thing:
a 94 3100 with a 95 pcm...make the 94 3100 quicker. lol.
