a burnt valve can happen from lack of fuel all the way to a exhaust leak on the headers.
ohh and what kind of intake manifold do you have?
mogs01gt said:soo that cylinder isnt getting enough fuel or the tune is running it soo lean that is burning up the valves.
Take off the chip and use the stock ecu. You dont have enough mods to worry about the stock ECU breaking anything.
Yea we can say its new (rebulit), ok so take the chip off, drive 500 miles, take it up for tunning. wont the stock ecu be affected by the 85mm maf and the fuel pressure regulator? Thank You for your help man!mogs01gt said:I take it that you have a new engine now? Yes I would drive the car around for 500 miles or more depending on your funds, then take it up to Steeda for your tune.
mogs01gt said:put the stock MAF back on when driving. That MAF is too big for your engine anyways.
stick with the stock MAF.
I think it was set to 40psi, but actually i read on mustangworld.com that i should set it to 30-32 psi for an improvement in high rpms.forpit2000gt said:what is the fuel pressur set at?

Heres the article:
How does an adjustable fuel pressure regulator give me extra performance ?
Fuel pressure is one very important thing in fuel injected cars. It controls how rich / lean your mixture is. During engine operation, each injector is opened for a period of time determined by the computer, the computer however can not control fuel pressure (unless you have a remote fuel pressure servo). If you purchase an adjustable fuel pressure regulator you MUST (in our opinion) also purchase a fuel pressure gauge (or you can't see your adjustments!) . Both are VERY simple to install and "very" easy to use (and cheap, both for under $200). We've installed the gauge on the fuel rail in the engine compartment so we can always check fuel pressure at a glance. Generally, you'll want to lower your fuel pressure from the factory setting (around 39 psi) to 30-32 Psi to give you a richer mixture at high RPM's for some extra bang.
should i leave 38 psi as stock or leave it at 40 psi, as the mechanic said?forpit2000gt said:Taking much advise from that site, no wonder you have problems. do not lower your fuel pressure.

Quit reading BS stuff from Mustang World and stop f#%@ing around with parts that are not correct for your car. My engine was built and tuned my Modular Powerhouse and came with a 12 month warranty. They put it on the dyno and check the tune before every race.MPH.
there isnt any reason to sell it. Just keep the MAF until you upgrade everything else. the stock MAF is good for the amount of power you are making. Any larger just gets you into more hassles and it could slow down air velocity coming into your intake.lordhell said:im not selling it, unless is absolutely nessesary, otherwise ill leave it there, i hope i can calibrate it with the chip.
