a simple retune after the 2.5 inch pipes and we should be golden!!

see ya soon...

I went in and checked it out yesterday, and I must say that it looks amazing. If anyone in the Tampa area is looking for a high quality custom exhaust I can refer you to a good fabricator.

Also, as I stated before the crossover pipes are still the same ones from the original turbonetics kit. I was surprsied to find this when I went in to get an estimate on the custom exhaust. I'm actually in the process of discussing the upgraded design for those with the fabricators. It should be a pretty simple process as the up-pipe itself was alrady upgraded and has a v-band to take it apart. Hopefully this will be done by next week.

And, to be honest and totally candid, after driving the car for a week I'm not really happy where its at. As I said before, it's still quite a way from actually being finished so keep that in mind.

The dyno graph you saw posted in my other thread may be a little misleading. I put it on a dynojet here in Tampa on Saturday and it didn't make nearly the power I had expected. I'm not sure what changed between when the car made big power at PF and how it's running now, but I plan to remedy it by finishing up the piping changes and getting it retuned. I also can swear the thing is detonating on pump gas at high boost. Needless to say I won't be pushing it until I get it fixed. Don't take this as a rant, just as the honest state of it since being quiet about issues in the past hasn't really helped matters.

I'm also a bit curious as to a sound the motor is still making. I've brought it up on here before, but it sounds like a metallic sort of knocking sound that a diesel motor makes. It seems to be coming from the motor. I'm a bit confused as I originally thought it was a cam chain tensioner that was fixed at PF, but it seems to be making the same noise now. I want to see if Chris can give me a second opinion on it in comparison to his car as he has the same cams as I do. I'm also not sure if it's "piston slap" as I've never experienced it before.

Let me know if you all have any suggestions. Thanks.

the car is not detonating, its those god damn injectors. i tried to tell you this a 100 times but you have some sort of issue figuring out what i meant.

i dont know if it is the injectors or some sort of problem with the utec keeping up with the 750s at higher boost levels but it is one of them.

I am still worried about that sound the motor is making. "Some motors just sound that way" doesn't really put my mind at ease, if you know what I mean... I'd like to find the exact source of it. It only seems to make it under load so I'd prefer to put it on a dyno and do some listening around. I'll have to try it sometime. It could be anything from simple noisy cams to a bad valve or rod bearing. I'm not saying which but the prospects kind of worry me.

The car is "pinging" no matter which way you look at it. I've heard it before on my old setup when the boost spiked. The sound is unmistakable like someone tossing bb's against the firewall. The tuner that dynod it on Saturday even mentioned it before I said anything.

I know you said the stuttering and unevenness on the top end is the injector pulse timing. If that would cause pinging then I'd definitely be interested in swapping the injectors out and trying something new. The car is definitely able to deliver enough fuel to keep the AFR's within safe levels, unless it's an issue with one injector inparticular, which could be the case.

The car made about 80whp less @ 18psi on the dynojet here in Tampa than it did in Orlando. The only possible explanation I could come up with was running pump gas and a lot less timing. This tells me there's still a bottleneck in the system (we know exactly where) that needs to be fixed. The turbo is still bottlenecked and making way less on boost alone than it should. IMO this is where I need to focus on before worrying about injectors, and I don't want to have to make power using pump gas and ignition timing. Hence, upgrading the piping first.

The cam gear will eventually break free of the keyway a bit and cause the valves to start touching the piston tops.....Then he is ****ed..

It idle it sounded like a loud injector "TICK"

As far as the injectors, unless one is failing I doubt it is an issue with them.I have tuned UTECS with 750cc's on 80% of our builds.The only issue we have had was hard starts when warm. The choppy graph maybe due to loss of spark,fuel or detonation.

i am sure you feel its really straight forward remove/install part but you checked that right?...just in case
