I recently swapped in some Crower 404's with the dual valvesprings and tri-nitrided titanium retainers in my 93 LS. I have literally every bolt-on there is, and now the car is bogging when I shift and stutters when the RPM's are low (2.5k or so). I spent quite a bit of money on the head and was orignally getting a code 3 (map) but got that taken care of. The idle is fine but lumpy or course. It doesnt really feel that much faster than my bolt-on LS did, though. Im worried and would like to know of some common problems with LS cams and bogging before I go get this thing dyno'd. Im worried al this dough I just shelled out is in vain!

 

bump, anyone?

 

up.....i have tha same problem n i would like to kno.

 

Have you guys brought it to a dyno to tune yet?

 

what header and collector size are you using? and definitly go dyno tune

 

Sorry to revive such an old post, but I found something out today. My car only bogs after the initial throttle input AFTER I have let off the throttle competly. Any ideas? Im thinking the ECU is severly retarding timing on intial throttle input...but I dont know why.

 

your prolly jsut runnin too ruch man.... you need to tune them there cams

 

get them tuned..my cousins LS did the same with your set up..kinda sounded like a hot rod

 

yea, it lopes like a *****....but thats one of the coolest parts...you should see the faces on mustang/camaro owners when they hear my little 1.8
