Guys it sucks i got my car tune by an local good tuner and made 260hp

So here it is
V3 link, fic 1050, with 2g head port and over size valves, kelford 272, 6bolt build, 91 pump gas.
Turbo is turbo lab of america
compressor wheel 53 x 71mm 11 blade gt3071r
turbine wheel 54 x 61mm 11 blade tdo6sl2
8cm turbine housing fully ported and polished, 37mm internal flapper
Internal gated
It had phanton knock i was told but these is realy low what should i do my goal was at least at 350
Is it realy bad to tune on 91 pump

Do you have a log to post up? How much boost were you running? I feel like it's your turbo that's the problem. Also what intercooler are you running?

Are you sure your tuner is really any good bro? What kind of timing curve does it have. Please post a log it will help us help you alot more.

I will post a log soon is that my tuner did it on his computer, and the fmic is an 3 inch core, the psi was 20 he also put a gallon of e85 to see if the phanton nock would go away

He is he tune a 600hp dsm, and the log i will try to do one soon as possible, he said the factor is the gas. Well is just that i want to know what could be my next move

Have you compression tested the motor?

No i am still breaking the motor. I am at my 700miles still i did the rigth breaking method of the 20 miles rings will set by accel and deccel with the motor breaking not using the breaks.

91 octane sucks balls. Like you expected, you should have a lot more power though. Need a log to see what's going on.

The knock is causing the ecu to pull the timing and you will have low numbers.

91 oct does suck but you should get a lil more than 260..

What are you using to tune? what injectors?

Profile shows greddy emange and 650s.. My best guess is the one of the two is limiting you.

91oct does suck but my car made 402 awhp on a mustang dyno on 91oct. I'm thinking something else is holding you back.

Post a log.

What was peak boost and is the car an A/T?

FYI, not every post belongs in the Newbie forum. This isn't our only forum and since you've got more than enough posts and have become a prove member I don't expect you to post in the Newbie forum unless you're helping someone. I'm moving this to the Dyno Forum.

What kind of dyno? Post the graph along with a log. Stock 2G intake manifold? Are you running speed density?

Read a little better and you will see what he has. We need to know what type of dyno.

Well guys thanks for the replys, and sorry for not posting the log thats the only way for sure to help me i will do one at soon possible, is just that whe use his laptop.

The intake mani is 2g, with the 1g tb maching, also the exhaust mani is an fp cast one. The head is ported. The car is 5 speed awd.
Can the factor be the turbo or maybe the tb not opening all the way.

The TB is opening all the way if the tuner knows what they're doing, that's one of the first things that should be checked in the log.

Again, what was boost pressure set to? I don't see anything in that list about ARP headstuds either and if that's the case you're not going to be making power until you upgrade the stock 11mm head bolts.

Here's a question I've got to ask...why is it that every single Turbo Lab equipped DSM always makes disappointing numbers?



Hmm.

Sorry yea i have mls gasket, arp 6bolt studs, and the psi was never pass 20. Cause of the phanton knock

Faulty knock sensor? Boost leaks? Are you running Speed density setup? I'm a newbie tuner, but I feel any boost leaks can cause low numbers on a speed density setup, along with any other air metering
Devices.

...that's why you didn't make any power, your boost level.

2g maf and hope is my sensor easy fix, also i have zero boost leak. Next time i will do speed density. When i get an chance a will do a log.

Is these true why are they more out there in my spot

Gofer
Well i will try it again with more boost but if it real knocks then i wont is just that with 9:1 comp should not need me to do alot of boost to make power. Next time i will tune with speed density and e85 with more boost just to see.
And also see what these turbo will do, looks like the turbo could be the problem cause is a new thing in the dsm world.

Not too shabby power for pump gas and low timing. You can always try low timing and disable the knock sensor with ecmlink to see if phantom knock is messing up your power output. Try 6-8 degrees at peak torque rpm range of 3500-5000rpm and 8-10 degree at 6-8000rpm. With a small turbo and a stock intake manifold, you will see peak power around 6500-7500rpm. Try 8 degrees for 20psi at around 6500-7500rpm. Make a pull and check the result. Add 1 degree at 6500-7500rpm afterward. You should see 10-15+hp gain with each addtional degree. If you are only seeing 0-5hp gain, you might be running out out of air flow or you might need higher octane fuel. Try not to experiment with timing at peak torque rpm with the knock sensor disable because you are likely to have knock there with additional timing. This is how I safely tune my car since Aem does control knock as well as ecmlink.

The stock 2g MAS is perfectly fine for that setup, power levels less then 500whp speed density is purely engine bay cosmetics or just a different means of tuning and has nothing to do with power output. Making the switch to speed density NEVER means you'll make more power, it's just that the stock 2g MAS doesn't measure airflow accurately passed 50 lbs/min (680 cfm). At that point you'd want to go to a GM MAF or speed density setup...

You're going to make more power running more boost and less timing. Did you happen to check your knock sensor or are you fine with phantom knock? If there's black goo coming out of the back of it you need to replace it and if it's loose it needs to be torqued to 17 ft/lbs.

Debatable:

Speed Density airflow difference - evolutionm.net

As for the stock 2G MAF not measuring past 50 lb/min, that can be fixed with the MAF clamp feature or an EVO MAF as well. I'd still prefer to just run speed density, if for no other reason than to be able to log post-IC charge temps to see if the FMIC is working efficiently.

You're right, anything's debatable even that post on a Evo forum you linked to. Without logs who's to say something else hadn't been changed? The OP never provided them like he said he would. To top that off, from reading what was posted, it seems he put down 480whp with a intake/MAS/filter and then went open turbo (meaning no intake/MAS/filter) and picked up 13whp. That's great but what was the restriction? If he had pulled the filter then removed the MAS and installed the filter, so the only thing he removed was the MAS, then you could say removing it freed up 13whp.

I'm well aware of the MAFClamp feature that Link has, we're trying to help the DSMer that made this thread why his setup only put down 260whp. Others were suggesting to install SD which is a big waste of money and I was explaining the why, running anything more than the 2g MAS in this case is overkill and won't give any gains, let alone significant ones.
