what to know what company makes best performance chip for engine and trans software for the mustang gt 05? also is steeda a good company? and when is ford racing parts coming out for this car?

 

elvism, Granatelli, Hypertech, SCT, F.A.S.T., all good companies, only SCT has something available for the 05 Stang GT right now. Steeda is a good company yes. I emailed Ford Racing about a week ago and haven't gotten a response back.

 

Have you actually tried the chip before? Does it make that big of a difference?

I wouldn't say so. My brother just showed me yesterday on another forum about this, another guy said it would be smarter and the best choice to get a programmer, then your dealer wouldn't find out (where as they would notice a new chip) and you would get about the same gains. The SCT programmer can get you ~15rwhp and 15rwtq, which isn't bad at all imo for $375. I'm interested in seeing what Granatelli comes up with though, I don't really like the fact of driving so far to an SCT tuner everytime I want a tune (which is only good for 3 tunes).

 

There will NEVER be a "Chip" for the 2005 Mustang. The current generation PCM systems cannot be "chipped". You have to download a completely new PCM program.

As nis350ztt said, as of today SCT is the only company who says they have a PCM programmer for the '05 Stang. Although I heard a 3rd hand story that someone got a SCT programmer & tried loading new software and his Mustang would NOT start after the re-flash. He had to re-load the orginal software (with great difficulty) so get his car to run agian. So maybe as of today NO ONE has a working programmer for the '05 Stang.

 

Always thought it would be more hp gain than that. My brother-in-law got a hypertech programmer for his GN diesel pickup and he got a 125hp gain and 150 torque gain.

 

Diesels tend to make crazy amounts of hp and tq with ecu tuning. Gasoline engines...not so much. I'm not sure why that is, other than I assume it is poor tuning from the factory, which may be to reduce emissions. One of the largest gains i've seen was Technosquare's ECU reflash for the Evo 8, it gained 40hp.

 

Not really. It has to do with the A/F ratio differences between gas and diesel. Gas engine must stay around 13 or 14 to 1 while a modern HPCR diesel starts out at 80 or 90 to 1 at ldle. From there, you just keep pouring' in more diesel until either 1.) you reach your hp goal or 2.) you melt down a few pistons because of high EGT. Since most gearheads think you can never have enough hp, it is usually number 2 that happens.

like v10 said no chips!!! reprogramming is an option but like stated above when it will be available is to be determined!

 

in the new jan '05 issue(just got mine) of 5.0 mustang&SF , SCT(superchips custom tuning) claims 20hp and 25lbs torque on a 2005 Mustang GT!!!!!!! The ad is on page 84.These guys are not far from where I live.I may go by there thursday and see what they have to say.

 

I'll have numbers for SCT probably next week. I get my car back from Flowmaster this week, and a local dyno shop is really waiting for me to get it over to them.

 

M1, Did you dyno your car pre-Flowmaster? If so, what was it?

Flowmaster is doing the before/after.

On top of that, a local dyno shop (with a Dynojet, vs. the Superflow at Flowmaster) is going to put the stock back ON, dyno it, tune it, dyno it, then Flowmaster plus tune and dyno. That should happen next week.

So we'll have lots of detailed before/after plus TWO Superflow vs Dynojet comparisons.

This should give all the internet bench racers some good fodder.

 

Great, looking forward to the results.

mmmmm, fodder

whats 'EGT'?

 

EGT - Exhaust Gas Tempature

 

Sorry about that, I answered that in another thread...

One overlooked component of the truck diesels producing such large gains with a chip or ecu program, is that the boost is usually cranked up on the turbo (provided it's an electronically controlled wastegate, or possibly vacuum depending on it's actuator). I've only seen really big gains on my turbo cars when 'chipped'. I did see a large gain on my naturally aspirated '97 M3 with the Dinan Stage 2 software and cold air intake alone, giving me 221rwhp with a car that was only rated at 240 at the crank from the factory. Using an assumption of 17% loss (probably less actually since it's a BMW and a 5-spd) I calculated new crank hp to be around 265-270, which is pretty impressive. This was on a Dyno-Jet. I still had the factory exhaust on the car and 56K miles. I think a good program could net the Mustang with a solid 25-35hp...but keep in mind that the Dinan software for the BMW's is only available at dealerships and was created with BMW. Aftermarket software will potentially be more compromised.
