Hi,
Have owned my 2010 MPS 3 for about 2 months now It has 80K on the clock. So far I have put the COBB stage 1+ kit on it straight way installed by HPF and it is just on a standard OST stage 1 COBB tune. The kit included: SRI, SF Airbox, TIH, and AP v3 (engine mount on back order for S2). It currently runs on stock boost. Got some nice gains on it, great improvement to powercurve and drives ALOT better, but would like a little bit more and leave it at that (not ever racing it) as stage 2 gains look very impressive.
Currently I am awaiting stage 2 parts to come in and get installed sometime next week by HPF. This includes the HPFP upgrade, downpipe and engine mount. I have some questions as I trust a multitude of people with experiences of there own rather than a company who sell a product (though they have been great and even offered me a loan car for the day!).
1. Anyone who has stage 2 out of the box, COBB only stage 2 kit (not a mix match), how have you found it? Is your car still reliable and driveable, and if so what kind of k's are you running to prove this and have you had any major problems not of your own doing?
2. Should I go with a custom tune, or just stick with the COBB OTS stage 2 maps. It will save me about $500 as i already have the AP v3. I am happy with the OTS stage 1 tune so far...very smooth drive. HP is not important to me, but I feel the stage 2 will give the car the best bang for buck with reliability still preserved.
3. I see the boost goes from 15.5 - 18.5 - Will the engine hold up to this over time? I am pretty conservative drive, no track interest etc, but I want my car to still last quite a few years. I rarely rev over 5K and let my car cool down for about 2 minutes every drive. I wait about 5 minutes each time before I rev it at all.
4. Is the engine mount replacement worth it. I have heard mixed things from brilliant to vibrations galore. I value my smooth driving fairly new MPS, and I don't want a shudder box or button clutch feel.
Any experiences, good or bad is welcome, but please provide detail. Don't say "oh it stuffed my engine" if you go to the track or are a frequent thrasher as this does not reflect my driving style. I would love to see my car hit 200,000km (turbo replacement of course) as I did with my sp23 (hit 300,000 with no rebuild, and it was revved alot!)
Kind regards,
Paul
