well i did my auto to manual swap and was expecting more power out of it. Ive driven a 90 gxl before so i know what i should expect more or less. But my car does not want to go....doesnt rev up to fast, im going to tighten everything up and double check everything but what could it be?

1990 gxl....rb header, 2 1/2 pipe single, cone intake. No other mods

compression is good....
cat is not clogged...

 

How was it running before the swap? You will notice a difference but not a huge one.

 

check the 6ports? I ditched the emissions and had to rig up a system that works great not. Now im just competing with bolts that are coming lose on their own, even if they have lockwashers on them
