this thing is driving like a$$ at low speeds 30mph or so even hard to pull of from a dead stop. when its cold it drives fine but once it warms up it sucks. its rough seems like i got accelerate through the roughness. but it dont respond to the throttle when i try to accelerate through, it like builds up then shoots off. its sounds nasty and has a sputter to it. if im going about 50 mph or faster it rides alot better. the shop said it needed a tiune. got it done. no change. then they said the opti has two parts a high and a low? and it was about to go out and thats y it was drivin so bad at lower speeds cuz the opti was firing all cylinders. i replaced that and still no change. any ideas?

your missing a cylinder.if you can try pulling the plugs wires off one at a time while the motor is running and do a compression test on all as well. need to find which is missin then you can look for the why.

i bought the motor already done. it was rebuilt and bored to a 355 with forged eagle crank, and eagle rods and pistons. the heads werent p/p. jus something to the valves and maybe something else. but they not p/p. so yeah i guess jus bolt ons and a cam. i thought the camaros came with about 300hp stock. it sure feels like more than 325. my tuner said its good.
what you get at a dyno is rear wheel horsepower and torque which is what you really feel.
I loved the 2005-2009 mustang guys who were mad when they took their 300 FWHP auto tranny stock stangs to a dyno and to be rewarded with around 240 RWHP. So, if you were at 325 RWHP that's not bad. But, was your engine acting this way when tuned? If so, there is more there once it's fixed
also, mustang(not the car) dynos are not as generous as dynojet dynos with numbers

Haha. That's if he's only missing on one cylinder. If more, I give the car props.
