Hey all,
I have a 2001 Bullitt with about 40k miles, its been supercharged its whole life, swapped pulleys, blown trannies, blah blah blah.
As it sits now, it is setup with a standard Vortech v2 kit, no fueling upgrades, no boost increase, everything as it comes from vortech for their standard kit.
When I was younger (and dumber) I swapped the pulley out for one one that upped the boost a couple of #s . I thought I would manage the system with a handheld tuner and just reduce timing and add a little fuel.
I didn't realize that the vortech kit came with a chip installed into the ECU, so when i tried to flash the ECU it wouldnt take the changes.
Ever since that, its run very funny. It will idle fine, but revving it, it almost sounds like it has clogged Cats, it sounds like its breaking up and just isnt revving freely like it should.
It will drive under its own power fairly well, but as soon as you push the gas, it sputters a bit then goes into, what seems like, a limp mode. The idle hunts up and down and the car will eventually die. During this you can't really accelerate.
No codes are thrown, except for the rare ignition misfire.
What are your guys thoughts?
Fueling? igniton? ECU fried?
I have been slowly putting this thing back together and figuring out this is the next step.
Thanks in advance guys.
