Need help just installed my chip!

[Bradley3054]

I just installed my tony wildman chip with six postion and when I put it on extreme, when I was 3/4 throttle or better my "service engine soon" light comes on and back off when I let off the throttle, can someone inform me why it does that. My engine oil does need changing but not for 200 miles more and it's still cleaner then my gas trucks oil and it's to the full mark. P.S. I have a early 99 powerstroke. I appreciate any help thanks.

May be your hpop or an overboost code.. do you have a scanner?

You most likely are getting an over boost code. When you let off your throttle the over boost situation goes away and there for the light goes off. This is common when running a chip. You can make a boost fooler with an air pressure regulator. Hook it to your air compressor set it at 20psi. Then with a couple barb fittings you can install it inline with the map sensor. Now your map sensor will never know when you go over 20psi and will prevent the cel from coming on from an over boost code.

^^ what he said.. there's a sticky in here telling you how to make a boost fooler, and easiest place to install it..

I understand what your talking about, now is this safe on my engine? Why is the boost guage only set for 20 psi anyways?thanks for your all help

The turbo is mapped to max out at about 25psi. With the chip you are hitting around 30psi when you are on the throttle hard in extreme setting.

The stock program is to run max 22psi. There for if you set the regulator at 20psi you will never go out of the normal range of.

Is it bad for the engine, not really how ever you could cause a turbo surge problem. Which will cause damage to your turbo. Which can be prevented when the time comes with the proper intake, and turbo mods.

You said you have an early 99 so you already have the wicked wheel. So when the time comes you will need the ats housing.

I have the DIY intake with the napa 6337? Or w.e number it is filter, what else would I need to do to pervent a turbo surge? What would need to be done to the ats housing? Is it really something to worry about? Sorry for all the questions lol just trying to inform myself more for my engines sake. Thanks

Are you running gauges, if not I strongly suggest you get some. Exhaust Gas Temp aka pyrometer, Transmission temp, and boost gauge.

For turbo surge if you start seeing your boost gauge flutter then you most likely have turbo surge.

As for the ats housing all you have to do is remove the intake housing of the turbo and install the ats housing. You can do this with the turbo installed. But you will have to disconnect the waste gate valve.

Yes I have guages and I was wondering what is the highest safest egt ur allow till damage? What's really the smarter thing to do I see they have so many upgrades for the stock turbos but wouldn't it be cheaper to just buy a performance turbo?

I believe it is about 1300-1350 on the EGT's and don't stay around there too long...
