I like the powerband on your car; its sooo phat! Its a wee bit of a shame your top end isn't better, but I think its obvious that the limit of the stock turbo on pump gas has been reached. This powerband shall serve you well for a long long time! |
Agreed on both counts! I was sick of complaining about the GM BCS because it never worked properly and I think this power level will keep me satisfied for quite a while while I focus on other aspects. The two main draws to the GM BCS for me were quicker spool and more power on the top-end, but on my car neither proved to be true. Spool-up is the same or slightly faster with a MBC, part-throttle boost response is much quicker with the MBC, and as we know my car did not respond favorably to holding more boost in the upper RPM range.
Although I don't think the GM BCS is a "bad" mod per say, it just wasn't a proper mod for me. My car saw no gain in being able to hold more boost in the upper RPM's since it seems to prefer timing up there, and boost is a lot more steady and consistent with the MBC. Plus, its much easier to adjust now. I'm still glad I have the JDM MAP sensor though and have no plans of selling that since its nice being able to log boost. I'll probably go ahead and plug the stock BCS back in for now so I can sell the GM BCS and not get a CEL (until I figure out how to safely disable that in the ECU).
