Poor acceleration 2000 ls1 in 36 Chevy

[Hambone1]

My ls1 slow from start and bogs if stomp accelerator at low speeds my v6 Buick will stomp the ls1. Had chance to do 5.0 ford wish I had for this type of performance. The 36 has 3.50 gears and auto from 2000 Camero SS painless wiring harness

Could be a number of things. Start with the basics - proper fuel pressure, adequate air flow into the engine, MAF is clean, no vacuum leaks, ect..

Second, are there any mods to the engine/drivetrain componants? Or is it a stock setup? If modded, please list them.

you need to give more information , what fuel pressure are you running , it should be 58 psi ,did you check for vacuum leaks , and don't be bashing the LS1 they will smoke a 5.slow

correct fuel pump?

[Hambone1]

I will have to get a valve installed on my fuel rails so I can test will let you know as for more details it is a stock 2000 SS slp motor with professional products manifold and a street and performance mass air and air cleaner setup

What kind of MAF? LS1s are very touchy with aftermarket ones, which very easily could be the source of your problems.

[lowrider095]

what about the fuel pump , what are you using

[Hambone1]

I checked fuel pressure it is 58psi at idle I can not find any vacuum leaks and the mass air is stock from street and performance I don't know what to check next the only modification is a professional products polished intake

Hook up a scanner and see if it is throwing any codes.

[Hambone1]

No codes were found

I don't know if all of you guys missed it, but it looks to me like he has the LS1 in a 36 body. The wiring harness alone is suspect.... Much less the PCM or the BCM.

[Hambone1]

The wiring harness is made by painless wiring so I don't think it is a issue engine runs fine and I have it up to 100 mph with no other issues other than acceleration at slow speed

[LoneGunman]

What plugs are you running? Wires? How many miles are the motor? Could be any number of things.

do you have a way to look at live data? Using the pcm that came with the engine? Can you look at fuel trims, timing, knock retard, ect ect? If so post up what those numbers are.
