I'm woundering if anyone knows where I can send my chip and CU to to get flashed. I spoke to American muscle and they don't mail order any blown cars or 5.4 engine swapped mustangs either . I have a heavily modded 5.4 blown car and don't know what to do. Also live in ME and no one here does dyno tunes at all

Also correct me if I'm wrong but I would think the 5.4 would be a diffrent tune then a 4.6 ???

If you are already driving the car I suggest you find the closest dyno and plan a road trip. With a blower you are playing with fire with mail order tunes

I am sure the 5.4 would be different because it is a larger cubic inch engine so it will require different fuel/air adjustments at least.

Research some handheld tuners.
Find the company who is most willing to work with you over the phone or through email.
AFM is very helpful with the PMS Tuner, so you might try - AFM SCT Tuner

Tune the car yourself with their help to at least get you a safe enough tune to be able to drive it to a dyno shop.
Otherwise you will likely damage the engine operating it untuned.

I have to agree with this 100%. You got the supercharger. Dont settle for anything less than a dyno tune. And a quality one at that... Road trip.

I honestly wouldn't even do a road trip. I'd have it towed or hauled to the nearest dyno cause you never know what will happen on the trip

Tweecer is a pain to use and no tuners want to use it if you decide to ever do a dyno tune. I have been through that already but as a program it is great. With somethin this complex it needs a dyno tine for sure. Mail tune wont be close and you dont want to even risk it. Hell i just blew up my 4.6 blown motor with a pretty safe tune so imagine what not having a decent tune will do

Protreeperformance.com. They are in NH but a good shop and about as close as you are going to get to ME. If there are any tech schools who do performance degrees or anything like that check with them. They almost always have a dyno.

Thank you all . I have lots in this and don't want to damage this one. The stock 4.6 pulled out had four cracked pistons all on the sane bank. I think that might have been cause by my last mail order tune but dunno for sure
