ok i have a 00 ss automatic with

Longtubes
4:10 Gears
tv2 cam 232/234 .595/.598
3600 stall
slp lid

also the second gear was slipping at the time but it went all the way till about 5500 then slipped so could that be why i only dynoed at 360?

i dont understand why it was only 360

 

Need more info. Stock LS1 intake? Exhaust setup? And why are you dynoing in 2nd? 3rd gear is 1:1 on these cars

 

stock ls1 intake had 2 1/2 trueduals dumped before axle dynomax bullets and thats what they did it in

 

The intake is chocking you a lot. Just an ls6 would probably add 20rwhp.

Also to compare number with most on here you need to run the dyno in third to have it 1:1.

 

If your an auto you should'nt be in 2nd. Also i have to agree with above dump the LS1 intake and what type of dyno machine were you using?. If its a mustang dyno you will definitly get lower numbers then the norm with the dynojets and dynapack machines but you also need to address the slipping issue as well.

 

You answered your question right there, taking it to 5500 is nowhere near where that cam will make peak power. You also have a stall and gears, so that will eat a lot of power on the dyno.

Also, keep it in 3rd otherwise you can't really compare numbers.

 

alright thanks everybody i needed something for closure becuase i went back and they said thats how much i should make i wont be any more and they said they can try and fix the tune for another 500$ i was like ah ill just leave it alone then lol

 

Dyno numbers mean nothing, especially in an auto.

 

You need a new tuner I'd take it somewhere else for sure,nobody dynos in 2nd gear unless you got a glide haha.

 

If you paid them to tune it the first time I'd take it back and tell them to finish the tune or give my money back

 

How much power are you expecting?
Sounds like your car needs some help before you start pointing the finger at the tuner. Get your transmission fixed which will obviously give you more power to the wheels, and have your tuner check your stuff again.
Did you purposely take your car to the dyno with a slipping transmission or did you find out it was slipping during the dyno run?

 

imo between having the ls1 intake and an auto that is slipping,and only going to 5500, that isnt bad at all, honest that intake is a choke hold , also i dont know if i missed it but what kind of dyno was it, 360 to the rear with those issues on a mustang are great numbers

 

no it wasnt slipping untill the dyno run then the tranny went out and now i have a built tranny but they wanna charge me another 500$ to retune and fix my idle becuase it wont idle anywhere i have to stall it up

 

They would charge you full price for another tune?! **** that place. Most people around here are $50 or less for a retune unless something very drastic changes. Sounds like the are a bit shady, maybe a bit stupid as well if they are dynoing in 2nd.

FWIW, my buddy made 351rwhp with an SS4000, torquer 2, 1 7/8" headers, LS6 intake, 98mm lid and a tune. The dyno is known to be a low reader...which was proven when he would destroy cars make 70+rwhp more than him. Like lemons said, dyno numbers dno't mean **** on an auto.

 

wow, my tuner does free retunes. but dont expect high numbers for a stalled auto, they are not dyno queens like m6 cars

 

Take a loss with your investment in this "business". If you paid them once and they can't even get your idle correct, what makes you think another $500 will make things any better? Run away and don't look back.

 

i know theyre supposed to be really good in Oklahoma but id dreather have a newby hp tuner give it a go then them lol im going to try one more place if that dont work then i guess ill have to learn myself

 

my car dynoed 414rwhp with a Yank 4200 stall so........

 

cool story bro.

 

Where did you go? Sounds like a crappy shop.

An honestly, if you made that much power at 5500rpm with a dying trans and ls1 intake through a stalled auto you should be fairly pleased.
