My Turbonetics Lean Dyno Runs
These are the dyno runs that I had from my TN install last week. I am now waiting for the UTEC to finish my install. This is a warning for people who install there own kit. You must have a widewand or put it on a dyno before you drive hard on it. I have a 2003 with a APS Plenum, JIC exhaust, and the TN turbo kit that is it. We even took the APS plenum off to see if that was the problem and it was the same.

We are going to shoot for 400 - 430 RWHP with the UTEC and the fuel system. I hope everything will work out smooth.

12.3:1 afr is as lean as you're going, which isn't too bad compared to some of the other FI dynos I've seen out there. Was the car detonating on the dyno?
You hit 395+whp on one of those runs, not bad numbers at all for the stock kit with the reflash. How high of boost were you hitting? Is the big exhaust causing you to boost higher and max out the 380cc injectors?

Tuan from GRD called TN and faxed them the dynos. They said to take off the plenum and the exhaust and I will be fine. We took off the plenum and ran it again but still was running lean. They then told him that I will be fine with that A/F and to leave it because they can't fix the lean condition only if it was rich they can make it leaner.
He told them that if the motor blew it was on him not them because he was the installer. So I told him to forget about the TN flash and there stupid fuel modification. I will buy the UTEC and a fuel return and have him tune it. I am very unhappy with the TN flash. I would have purchased the tuner kit and saved money from the beginning. Oh well.

just FYI a Good majority of the ECU cannot be hacked by TS,TN, AAM only partial areas they are VERY LIMITED thats why a UTEC might be a sweet taste in our FI mouths. AEM also =)

There are so many things I am hearing about my car. I almost wish I never turbo charged it. It went from $6000 to almost $9000 now after I will be done with the UTEC and the fuel system. I never planed on spending this much money on this kit.
1) Free flowing exhaust
2) high volume intake plenum
3) Freezing tempuratures in Chicago
4) No electronic or manual boost control
edit: just saw you posted while I was typing. dunno then

With all of these variables, I think its a given that it's going to run slightly lean. Now, what is the max boost the car was hitting on the dyno?
