No, I mean the turbo boost. Most LLTs are running at 6lbs of boost. I am now running at 10 lbs.

There alot more to tuning a car that is running rich, than just upping the boost. That was an over simplification. The mindset of Tracy was if this thing is getting plenty of fuel, lets give it more air.

very impressive. im guessing @ 10psi you are around 450whp??? i will strongly recommend Meth injections if you dont already have it. Which will make the car even more rich but it makes it much safer, Keeps IAT down, and cleans everything while you are at it. No tuning with the meth. Just get to a decent AFR and then add it on.

Did you get any feedback on how and when the turbo is responding?

He was talking about the fuel pump. There's two fuel pumps on the LLT. one in-tank, and the other up at the engine for the high pressure injectors.

any updates?

any updates?

That weekend that meth was suggested got me thinking. Meth really would be a good idea about now. I asked Tracy's wife about adding Meth while it was down there. She replys "No worries, we'll set the boost controller to 7lbs, but the 10 lbs is there if you need it. It will be plently safe"

That really wasn't what I wanted to hear. I wanted it to be tuned to run at 10lbs all of the time. Tracy got back to me, and said I hear ya. He is going to put in a custom meth injection system for it from Alky Control.

He also said that he is able to get it to 12 lbs with no fuel issues. It took a little bit for the meth system to get ordered and get to Tracy's shop. It actually just got in today, but everything else is done.

I am going to fly out there Saturday, March 30th to pick the car up instead of transport it back. I got tickets dirt cheap, and I also did want a chance to drive it around a bit in Florida.

Sounds great, hope you have fun on the drive back !

I think thats a very smart move with the Meth. There really is no downside to it if you tune correctly and just makes it safer overall. I cant wait to see this thing driving as i know how hard it is to get these running right under boost. especially that amount safely!

too bad you are missing opening weekend at the track, but i think you will be having more fun cross country regardless!

TTT- curious on updates? how was the ride back.

Well thats good to hear.

My setup is a 1000 times better than before, so overall I am very satisfied.

I do however have one issue. My turbo and set up work phenominal up to about 90-95% throttle. I'm running at 12 pounds of boost, and I can hit it very quickly. My issue, which is perplexing to me, is that if I go WOT, the boost comes in slower, and it will hit 11-12 pounds, and then drop off to about 1 or 2 pounds.

Tracy thinks the MAF sensor is failing, even though it works at near WOT. I have a new MAF sensor, and will be putting it in today or tomorrow.

Here are some clips of some videos I took on the way back:

Does the boost drop off while at 90-95% throttle?

A lot of cars actually lose boost at higher rpm. Trying to see the connection between a MAF and losing boost I guess. The Turbo wheel should still be spinning fast enough to produce the peak psi. So unless its due to Turbo size or high IAT. That's a good one lol

sent from my galaxy s3. that would explain the errors.

Nope, the boost doesn't drop off at all at 90 - 95 % throttle. It is also way faster than my car has ever been at WOT, even at part throttle.

couple things i would log would be fuel pressure, IAT's, and timing.

My guess is the car is pulling timing at WOT for some reason causing exhaust flow to lose velocity which could result in boost drop.

possibly too much knock at WOT too.
