The automatic 4.6 3v Mustangs work well. It's only when you get above 450rwhp that it gets iffy. As a stock setup it's fantastic imo.

Cat delete messes with the LTFT. Unless the ratio from O2 1 to secondary O2 is changed you will have issues. Unfortunately custom tune places will turn the MIL? codes off to get around a bad tune. My apologies for not remembering the proper nomenclature. It is something I've dealt with in...

Air that hasn't been metered is where I would start. Vacuum leak or something with the air intake. An aftermarket cai could be the culprit as could a dirty maf which would replicate unmetered air to the computer. You already cleaned the maf and basically have covered all the bases. Maybe...

So an update to this is that SCT couldn't figure the problem out. It had something to do with an OS computer upgrade. I finally got it back with a new computer and a new download of the SCT software. The problem started when I installed a ssd, something didn't get transferred from the old...

I don't know of a code. It's old school from the time of carburetors on a day with temperature extremes. We would open the gas cap and hear the vacuum being displaced and all was well. I've experienced it once with a FI motor. It's just a thought that might help.

Aluminum block is preferred over the iron. It will hold more hp and is lighter. Stay away from any stroker unless it's using a Ford crank, the power difference is minimal and the stock Ford steel crankshaft is very strong. I've built several 4.6 and Big Bore Boss modular motors and can tell...

That sounds exactly like vapor lock. By any chance do you have an aftermarket fuel cap?

Yes. Any vacuum line will also be subjected to positive pressure (boost). Something to keep in mind is that you will only see boost under hard acceleration. You probably already know that but sometimes people don't (myself included when I first put a Whipple on my motor).

It's possible that the pressure relief valve in your georotor oil pump is relieving pressure. I would ask if you use the specified oil weight? Using a higher viscosity oil will/can result in the pressure relief valve opening and starving your motor of oil for a brief period of time. It's my...

I'd say keep the car until you don't want a replacement when it goes away. Then you will be done.

Thanks.

The fact that it worked for many years with McAfee is what caused my doubts. The root issue is that I did a ssd drive swap about 1.5 years ago. Ever since then I would have to .exe from program files because a few hidden SCT files wouldn't copy over. The easy fix would be to uninstall...

So, I've been having issues with Advantage 3 tuning software for awhile. Did a remote hookup with SCT and when they couldn't figure it out they told me McAfee doesn't work with Advantage. I did tell the tech that it only became a problem recently after 9 years of success with both programs...

I have a set of California Special mufflers. $75 plus shipping. Be advised that shipping costs are out of control.

Seat of the pants feel is usually nothing more than the commanded torque table. Changing the accelerator pedal feel by commanding more torque with less pedal will make the car feel faster but it won't make it any faster. It mostly makes the car harder to deal with in slippery conditions. I'm...

Correction! When I wrote "a-arm" I meant K member.

FWIW I sold my car yesterday. I asked a very reasonable price and sold it for my reasonable but firm price. What really kills me are the Pawn Stars fans who would offer less and who obviously didn't recognize a good deal, then would get upset that I would say "good day" and good luck and not...

I always had to clock the transmission to about 2 o'clock to get it in. Also remember that the slave cylinder is going to fight you. If you have extra long bolts for the motor/trans then use a couple of these to draw the trans in until normal bolts can be used. I also found it necessary to...

So how does nitro work? It has it's own o2 and that's why so much can be pumped into a cylinder without filling it with air and still ignite, at least that's how I understand it. What I'm wondering about is how important is stoich when using it? Is it one of those fuels that doesn't really...

Well that's it. Sold the car this morning. I'm sending a link of this thread to the new owner. If he posts please be nice. Bruce

SOLD pending pickup and money transfer.

This^^^ The thread design will seal it. Put the stock cats back on! For crying out loud they work well. You can always get a set of high flow cats. If you still want to have long tubes then put high flows in the h-pipe and have a tuner who knows that the o2 bias will change with the cats...

It will work out for you. Not sure who the vendor is but if they don't ask for datalogs and provide the livelink files to do the logging you probably don't want to use them IMO.

FWIW usually the alt and battery have to be replaced at the same time. I've used a parts store rebuilt alt without issue. It has a lifetime warranty and worked great. Ford doesn't have a good track record with these alternators and I wouldn't put up the money for one from a Ford dealership...

I think you already hit it. Either the clutch pedal isn't far enough down or the sensor adjustment isn't right.
