Prodigy Performance 3.6 Turbo DIY Install

[AGOM]

Pickles,
im not sure what the problem is but I'v looked at the obvious as much as I can and now I'm thinking it might be something deeper.
I used to love the way the turbo sounded when you put your foot down and you get that distinctive whine followed by the whoosh when you release, but recently when I accelerate the whine is now mixed with some whoosh ( excuse the funny talk but I have no other way of explaining it) also while accelerating the car tends to hesitate, feels like it's beeing held back at times, and at cruising speed the boost comes in and out, you can hear the turbo spool up and release even though I'm holding a constant speed on a level road and no wind.
Also something weird happened to me on the highway, cruising at 80mph 2800RPM 5th gear the temperature starts to increase at a steady rate, had to slowdown because it didn't look like it was going to stop increasing, this is what I don't understand, same speed at on 4th gear RPM 3500 and the temperature starts to backdown and sits dead center on the gage, tried it again on 5th same speed temp up select 4th higher rpm same speed temp comes down.
My lack of knowledge in terms of reading or maybe interpreting the logs dose not help in getting my point across.
I will try and get a log to you by tomorrow and tell me what you think.

If I were you, I would record a data log of those exact situations you described, and send them to Prodigy with a description of the problem.

Do you have the 6-speed manual transmission? If so, then what about driving at 80 mph in 6th gear? I drive 70-80 mph in 6th gear all the time without any trouble.

When a turbo feels like it is going on and off that is called Compressor Surge or sometimes just Turbo Surge (the first is more correct). That happens because you are operating on the left hand boundary line of a Turbo Map. It is an area of massive instability in the in the pressure on the compressor wheel. And why you see it in 5th gear is probably because the cars throttle is too closed off so you are getting back pressure in the intake manifold causing an instant build up of extra air in the process-- this creates areas of high pressure and low pressure-- this causes the compressor wheel to create boost and then stop creating boost. I know this engine isn't a throttle body type system but it still has to control the air flow into the cylinder heads some way. It seems that is not working correctly. So, why does vanish in 4th ? The throttle is opening up more in 4th Gear to allow more fuel and air to mix and this gives the turbo the ability to pump all that air into the cylinder head. Why this didn't show up right away is sort of a mystery. It could be that your tunings some how reset to stock and you need to reset them. But I don't know much about your settings so those claims are hard to make by some one like myself. I would just take it to a mechanic have him test it out and see what he says. I bet Compressor Surge is what you are describing and it will cause the cylinder heads to trap excess exhaust cause if it is by an intake blockage. It could be a valve timing issues too-- the VVT system is some how cutting off the flow from the intake too early and causing the surge. Compressor surge is not good and you should have it corrected as quickly as possible.
