I have recently added a BAT intake, new plugs and 9mm wires, Unorthodox Racing pulley, MSDS headers, SHO Shop off-road Y-pipe, and Bosal cat back to my 2000SVT. I took it to dyno today, and only pulled a 168.1. What is wrong? Any suggestions appreciated.
hey now I don't feel so bad, I only pulled 167 the other day with the mods in my sig.
Did you get a wideband O2 read out? That could help us a lot.
No, I didn't. I am not sure how new the dyno was. It actually looked a little rough, but I am supposed to go back next week because the guy was going to burn me a chip after the dyno run but his computer crashed. Any suggestions you make could really help though, thanks.
How is this guy going to dyno tune a chip without a wideband O2? What kind of software is he running? How much is he charging you?
have you ever cleaned the intake manifolds?
the guy has been in business for 15 yrs but only did mustangs and grand nationals until recently. he is charging $450-$500 for the chip and dyno runs. i think he is using some software from diablo.
When should you clean the intake manifolds? My car doesn't even have 30K on it yet. Are they hard to clean?
I highly doubt even a cleaning of the IM's would compensate for such low numbers. With those mods, 180 or higher should be about right! Get in contact w/StreetFlight, they can custom burn you a chip and they've got the experience with our cars which is a big +......Wait KEYSER which is posting in this thread works there, PM Keyser...Aloha
I pulled at another dyno today and managed a 170, but I am still pissed. I should be pulling way more. Any ideas as to why the numbers are so low?
try a different dyno...I know I will when I get a chance.
Did you gap your new plugs properly?
My best guess - it's a 2000 SVT running hog rich. Get some O2 data to help you out.
Ok, the guy that dyno'ed the car last night gave me some print outs and said that my F/A was 'fat' all the way through the power band and said a car like mine shouldn't be running that way. he said it needed to be atleast a whole point leaner.
as to the plugs, i did not put them in, but a friend of mine who is a mechanic for a living did. i just assumed he knew what he was doing and gapped them properly.
If you have a print out of the air fuel it can be repaired by a chip much more easily. You also have some fuel multipliers in there for cat protection and other BS that can go away to make your car more consistant.
Can you post a copy of the dyno run?
