When I was at stage III UTEC and was dialing in the abc, I inadvertantly got boost briefly up to 19.3 psi.
Two weeks ago I got the stage IV install with an 18g and an aftermarket turbo inlet hose, then a week later a tune. On the dyno I couldn't get over 13.9 lbs, but during the road tune the tuner got it up to 17.5.
The car's a beast and the tune's smooth, thanks to the work of the top-flank tuner who flew in for the week. I'm having a blast driving it, but...
I was expecting to have to restrain myself from setting boost in the 20s, not to be wondering why the heck I can't even reach 18 psi.
Turns out the brass restrictor pill between the compressor side of the turbo and the stock solenoid is missing. If this is the culprit, I'm figuring it was tossed when the turbo was installed, given my stage III experience.
I've searched the boards and read all about the pill that's out there. Here are my questions to the helpful and knowledgeable, with my thanks
1. Do you think it's the pill, or do I need ebc or a beefier solenoid?
2. How involved would it be for someone who knows their way around a UTEC to modify the tune if I put a pill back in?
3. If this were your ride,
what would you do?
a. put in the pill and let the tuner talk a less experienced but local pro through the mapping adjustments?
b. wait six months to a year 'til the tuner comes back to town, then spend another bundle on a new tune with the pill?
d. forget the pill and be happy with the great tune at 17.5 lbs?
4. Aside from the UTEC map adjustments, could there be a downside to getting back on the pill?
