got car tuned and it runs like complete sh*t

[1trickedpony]

got my 95 gt tuned today. Has e-street heads, steeda 19 cam, #24 injectors, 255 lph pump and 3.73s. I had the guy tune the egr stuff out because its gone and it only made 235.19 hp and 281.74 tq. it drives nice just normal rolling along but if you mash on it, it seems to hesitate and then make a popping noise then its goes. Before the tune it would only pop if it was first start of the day and the car did not warm up at all and i stepped on it. I have steady fuel pressure at 41.28-43.32 psi. Any ideas what is going on? I can take it back to the guy which i plan on but idk if there is anything I can check to see what went wrong here before I call him up to complain. I put new plugs in it (autolite 3926's) with a .054 gap... could that be the problem? The car used to pull pretty hard from about 3200 up to redline before the tune. Also the idle wants to hang at 1500 rpms after cruising for a while and coming to a stop... I am open for suggestions.

That sucks man. You paid for a tune it should be right.

Dam that's beat.

 

[Noterminator]

Take it to Doug next time.

I have done some work on the car but we don't do EFI tuning. Carbs, nitrous and suspension tuning is my specialty.

Definitely get on the phone and see what's going on. I would be pissed if they tuned it and it still ran like shit and the numbers aren't where they should be. What maf are you running? Did you see the dyno runs or no?

Oh ok. He might wanna go see Brent from Brenspeed then lol. Long ass trip ha ha, but he does amazing work with tunes. Or he could try JPC racing. Around here there's only Redline Motorsports, but they usually stick mostly to Chevy's, but they'll do Mustangs if they have to lol. Either way I would make them fix it, then never go back there again.

 

[onlycodered]

You may also want to talk to TheTunerGuy on here. He's flipping amazing with tunes!

Howard Tanner (Redline) has moved to Florida (awwwwww). You wouldnt want himdoing it any way, better off driving 3-6 hrs to some one who know how to tune Fords.

 

[EHA Racing]

I've had some lengthy conversations with Mike at Powerhouse 411 in Erie, Pa. Very knowledgable and only tunes Mustangs. I'm bringing him a car to tune this coming week. If all goes well he most likely be the tuner my go to guy for EFI stuff.

Yea Brent is probably one of the best. I don't remember the guy's name from JPC but he has like a 8 second s197, so I'm sure he would def hook you up right. New York has some decent ones, but too many are car make/ model specific. I hate that shit.

Awesome. Looks like he might be able to stay local then.

Its not the map or fuel pressure... although they could be bandaids to temporarily fix it

 

[c's06stang]

if you have cats.... take a peek at them

 

[1trickedpony]

i dont have cats anymore. What is odd is I flipped the chip over to a different tune that BAMA sent with it when I bought the chip last year and the car pulls well on that tune. I have a feeling he fucked something up big time. I dont think i mentioned where I got it done but i had Kennedys Dynotune do it... everyone gave them such great praise I thought id go with it seeing that I want to put together a better bottom end this winter and wanted to have it run up to its potential for the rest of the summer. i'll keep you posted on what he has to say.

Btw Doug you should get into this efi tuning thing!

 

[dsblk93gt]

That combo should run good without a tune even. Its really mild. I would have to say you may have other issues. Have you tried cleaning the maf? What did the a/f look like on the dyno? What maf are you running?

​

 

[1trickedpony]

i cleaned the MAF the day before I took it and changed the plugs too. going to drop the gap slightly see if that helps at all. I am running a c & l maf calibrated for #24s the dyno sheets say Max *Air Fuel R= 15.20 but on my wideband it hangs out around 13.8 to 14.2 with normal driving but when it starts to pull hard its around 12.4 so idk what the deal is. I am not happy with it. any ideas?? anyone wanna take a crack at it?

Get another tuner... I have a good idea of what it is, but you need a tuner not an internet post.

 

[newguy]

would say get brenspeed too, but maybe you need dyno tune??? should prob ask whoever did it to straighten it out first?! let us all know how you make out!
