Ok so here's the deal. I went to S&S performance and had a dyno done now the #'s i got are 232rwhp at4800 and 279 rwtq at3800. At the time i had flowmaster(not slowmaster)catback,k&n cold air,vortech elbow,180 thermo and typical free mods. I found the fuel filter was bad but could it choke the motor that bad??Thx for replyin...btw this is my first post

 

Not sure if you have an automatic or not, but those sound reasonable. If you have a manual, it seems low. Judging by the fuel filter comment, maybe you need a tune up?

 

Yeah it is a auto but no worries i did all the filters and fluids and greases.. she's runin pretty right now

 

My stock lt1 did around 240, then i had an intake and flows and it boosted it to 266. Your numbers sound right

 

ok i was worried for a sec. especially with the 275 thread talkin about 266 and 270's stock. much appreciated relpies guys

 

Not trying to burst your bubble but I had a Mac catback, K&N CAI, and Ed Wright tuneing and put down 278 rwhp 305 rwtq with an auto.

 

I still think his numbers are a little low.

 

Were those numbers peak? Did they go down after 4800 RPM? I believe your numbers are probably close to average. If your numbers went down after 4800, you probably just ran out of steam. Nothing that a CAI, RRS, headers, etc. couldn't remedy.JMHO
