I have a 95 LT1 that is guttless until about 2500 RPM. The previous owner told me it had a small cam, flat top pistons, bigger injectors. I know for sure the car has BBK headders k &n intake MSD opti and wires. anyways the thing has no power off the line untill about 2500 RPM, what would cause it. Would a bigger T.B. help? Thanks

 

Does it feel like it's missing or bogging? It might be that you need a stall. Cams and stock stalls feel sluggish below 3k. Don't know about "gutless" though.

Regardless you need a stall.

 

Describe exactly what you mean by "no power," because that means exactly zero to us oblivious LT1 owners sitting behind our keyboards.

A bigger throttle body will not solve your supposed lack of HP.

Any stored DTCs? Fuel pressure good? How about coil/plugs/wires? Any ETs proving that you're down on power? Has it been tuned? Lots of stuff to consider.

 

Your new sig pic is sweet.

 

what rear gears?

 

The car is a M6, I forgot to say that. Although the car does seem to "bog" untill 2500 ish.


There are no codes, dont know about the fuel pressure I will check later today, The plugs/coil/wires were just done befor I bought the car, although dont look the newest. Not sure about the tune. Is there a way to tell? (Under the computer hook up there is another computer hook up looking thing not sure what it is for?)

The door says it should have 3.42: 1.

Thanks for the replies.

 

I bet it hasnt been tuned for all the mods.

 

Is there a way to tell?

 

If it weren't tuned it would read a code or 2 wouldn't it??????

 

My last car had a hotcam installed with no tune and I didnt have any codes. It ran really rich but never threw a code. I dont know about bigger injectors though, Ive never ran big injectors with no tune.

 

The car is running rich.

 

How do you know?

 

I can smell fuel in the exhaust
