You probably wont get much out of the dealer if months have gone by after the work was done. Its worth a try though.

I really want you to dyno your car because I was searching some other threads and saw that the Arma supercharger kits on a IS250 dyno's at 312hp. Thats about 30-40HP more than a IS350 with full bolt-on's.(actual HP, not crank HP, most IS350's with full boltons dyno at 270). I wonder if you would even hit the 300's with your TT. Most 350's with superchargers dyno at 350-355hp. Higher compression engines with turbos cant be forced much but will make more usable power through out the lower to mid range which might make the IS250 the better car of the two to boost. 312 is more than 130Hp gain. You may do better than that.

It hits 312 whp in ARMA's dreams! That's all I'm going to say! LOL
Ask them about the added fuel injectors and how they control them. Also, ask about the dynos. LMAO

If you want to know about most likely the highest HP IS250 out there msg. Elias from Greece

About the stock headers, just make sure to tell them that you DIDN'T have them on there with the turbos installed. Should help your case.

Anyways, did you get the ebay headers installed?

Lol I'm with Mike here. You won't be breaking 300whp. Not even 250whp at 6psi unless you're on a very liberal dyno. My dyno numbers were low because the dyno jet I ran on had 4000lb rollers where as our cars weigh significantly less than 4000lbs.

Header install was finished today. Took the mechanic 9 hrs to complete the job. All I can say is that it sounds awesome!!!! Turbos spool up way quicker which makes them seem louder even at idle. Wouldn't recommend headers for those that are looking to have a quiet drone free car. The car feels faster as well... Not sure if it has anything to do with the fact that I haven't driven it in 3 days lol

I'll make a go pro video tomorrow on my way to work and upload it as soon as I get to the office.

So what boost psi are you seeing now? If lower than 7.5 (you're earlier mentioned target), are you going to tighten down the internal wastegate rods to net you that slightly higher psi?

Can't wait to hear those babies spool now!

I'm only spooling at like 2.5 lbs right now. I found out one of the turbos got damaged when the cats fell apart and a chunk of the cat went into the impeller. It spins but there is a ton of shaft play and bent fins Gotta buy a new turbo which won't be happening till next week because I'm broke. Lol

Don't like to put any of my mods on a credit card but if it bugs me a lot I'll probably do that and buy the turbo...

Here is the video you guys have all been waiting for!
This is just a typical drive on my way to work. Not boosting at all which is why you can't hear the turbos spool. The cops are really hot around my area as I do pass through 2 high schools and a police station on my way to work.

Sounds really good. When you change the spot of the turbos, are you going to put mufflers back on?

I've always had loud cars so I doubt I would put the mufflers back on. Maybe a resonator if it's too loud. I love the sound these catless headers make! The turbos sound so sick when they start spooling!
