With 240-250hp boost creep may be inevitable. i.e. it may not be safe or practical with the stock turbo.

Fortunately it's not too difficult to install a larger turbo At the time of this writing, custom fabrication is required to install a decent sized turbo upgrade.

I'm prety sure you have the same 1900mbar stock hpfp like I have the 2010+ CR went to lower mbar units for production cost and will require an hpfp upgrade I would imagine on my stock h pfp and injectors there is a ton of more fuel left for power. I have an very aggressive tune they puffs black smoke on startup as well while wot.... my egt limit was raised and on the dyno with an 43f temp day I pegged 950c temps from 3k rpms all the way to redline

Malone I need to get with you on maybe modifying my tune on all 3 pulls I spiked 31psi @ 2300 rpms then it tapers back down to 26pis and holds that solid.

Storx e-mail me (see signature below). We'll decide between tuning for less power (keep the stock turbo), or start with a bigger turbo

I am waiting for the bigger turbo setup as soon as Kyle finishes it. The only problem I am having is its spikes 31 psi then it bounces tell the boost gets under control. Also I noticed I dropped a significant amount of tq when I unhooked exhaust from stock pipe and dyno off just the downpipe. Do u know if my tune is setup more for factory exhaust or full flow?

Your tune is set up for full exhaust flow. If you send Kyle or I an e-mail we can arrange a tune update to lower your spike.

Ok, I will after I get back from my road trip. Leave this Sunday for 30 days to drive the entire country to see family I not seen in a long time since been in the military. I will be putting about 3700 miles on the car... Hopely by then Kyle will have the big turbo kit ready for me.

I'm not to worried about it... It doesn't get that high driving it normal... And my tune is setup to stop boosting past 950c but the turbo is rated for much higher egt so a few seconds shouldn't hurt it..also I'm going bigger soon so the trial and error should be fun

If it gets to 1700*F+ by 3000 rpms, you may be well beyond that by the time you're at redline. You need a gauge with a higher limit.

You know when you see your fam you won't "drive it like normal" when they ask to take a ride. I'd be careful with those EGTs.

The EDC17 ECU automatically limits fuel/power if the EGT limit is reached.

storx wanted a 950C EGT limiter and that's what I set for him.

Egt was taken from vag-com log and when I drive in the mountains or pull my atv I not seen danger egt the only time I did was on the dyno and even that was only on the last few runs. The first 2 runs barely got above 850c.... The worst run was the 7th run and it pulled just as hard as the last 6 runs. Also something to consider is the IC actually didn't show much heat soak. The first 3 pulls were downpipe with stock exhaust flapper back and last 4 were with just downpipe and all 4 were within 5% of each other
