80mm is a 3in exhaust. I'd be expecting you to hit 9-9.5psi at least running from the wastegate with the stock 8.5psi spring.

By the way, did your turbo come with the Turbonetics logo in red like that? Mine didn't.

 

I always thought that it was an 8lb spring included in the kit. I guess I will have to check it when I take it back to GRD for the UTEC install.

The red Turbonetics logo was not like that when I got it. I saw the picture of the turbo in the Turbonetics advertisement in the forum and just took red permanent marker and filled it in. I will post an up-close picture of it.

 

You might be right. I've heard from most that the kit runs around 8.5psi on the stock exhaust. I guess the difference between 8 and 8.5psi is just a small difference in springs, so it doesn't matter too much.

Nice mod on the turbo though. I was thinking about painting something in there with some high-temp paint but it would be really hard with it already on the car.

Its not really all that lean. Just a bit. Have they thoroughly checked for leaks in the intake path? Have you checked your fuel pressure at all?
I wonder if a 7psi WG spring might knock it down a bit. Its worth a try.

Sorry you are so upset with your car and having to spend more $ than expected. Just remember with FI stuff happens.

 

I know of a few guys with free flowing 3" exhaust, one guy I know of even has a crank pulley and a plenum and his A/F's are safe. Seems like some ECU's adjust to small mods and others seem to lean out after the flash.

This is exactly why I think TN should include 1 additional reflash to the customers who will occassionaly get a lean or super rich tune. Did your installer ask if they would reflash for you? Now you have to spend $$$ on a piggy back and imo that is taking away from the attractiveness of this kit which is to bolt it on and go...

 

Would you drive your car with the AFR in the 12's on boost? I sure wouldn't.
We have not checked the fuel pressure because Tuan said there was a part he needed to order in order to check the pressure and he didn't think it had anything to do with that.

And for the 7psi WG spring, I was running from 8 - 8.5 psi of boost. That is what the kit is made to run. I don't want to pay money and run less power than most people on here with the same setup. That is just a band aid fix. Also you are right about with FI stuff happens. I just didn't expect to pay this much. But im sure I will be happy when the car is running right.

 

Yes my installer asked TN to do another reflash and they said there was nothing they could do about the lean condition. They told him to bolt on the stock exhaust and plenum and give the car back to me. That is BS. I want to run the exhaust and plenum that I purchsed. I guess the flash is hit or miss.

 

Wow that sucks-I think they should def reflash your ECU., If anything they should deny a super rich flash of 1 additional reflash, because they can say its "safe", but to deny a lean flash, and tell you to take off 2 mods that many other TN cars are running with no issues is dumb imo Good luck to you....

 

I was not suggesting you drive it in the 12's but being that your only in the low 12's briefly on that dyno it looks like you could bring it down a bit (maybe with boost or fuel pressure) and be good to go.
The thing is, right now you are making considerably more power than any of the other TN cars (stock kit) so if slightly less boost brings the A/F into scope and the power stays within the kits published bounds then where is the problem? In fact wouldn't it be better to make 400whp at 7psi if you could?
I understand that you want as much power as possible but don't expect to get it without paying for it one way or another.
I also wonder why you are making that much power. Other guys including myself have 3" exhausts, crank pulleys, and lighter flywheels etc. and not making near that much power.

 

Its a dynapack which reads higher than a dynojet. Local Z's here dyno 20-25whp higher on a dynapack over my baseline on a dynojet. If you take that into account then hes right where he should be.

 

You always say that Dynapack is higher and everyone else says the Dynapack is lower than Dynojet.

 

according to tuan, their dynopack dynos lower. Said my car would be about 20-30 hp higher on a dynojet. This spring I will get my car on a dynojet and compare.

 

I go off of personal experience and proof, do you? Or are you just going off what people say? I dyno 240whp SAE corrected on a dynojet. Two local Z's dyno'd 258 and 261 bone stock on a dynapack SAE corrected-think what you want, I dont want to jack this thread anymore

 

That is what GRD told me also. I don't know how much lower it reads but it does read lower than a Dynojet.

 

I guess your right. I don't know. I don't have proof yet.

 

Now wait a minute here. I'm not going to start a flame war but I asked you if Turbonetics REFUSED to reflash and you told me they did not that you just were done with it. Are you saying that Turbonetics told you they would NOT reflash the ECU? If so I'd love to know who told you that cause I'll call them right now and find out whats up with that.

 

Mia to the rescue....I also understood it that he was done with the flash idea, thats why I asked for clarification. Either way, Im glad to have such a helpful person on the boards

 

Thats what he told me. I have NEVER heard of Turbonetics refusing to reflash on ECU if there was a problem. I mean NEVER. If someone told you that you better believe I'll be letting Brad and Reggie know.

 

Awesome I was just thinking "I hope my car with a crank pulley, plenum and 3" exhaust doesnt run lean." So you are saying that TN will reflash your ecu again if your original tune is dangerous lean even with mods? I would hope so because like I said, most do have exhaust and other mods and are fine on the original reflash.
