After pulling my car out for Spring I proceeded to setup a dyno pull. (I
had added an intake spacer, removed the heat shield on my C & L unit,
and added NGK tr55's) hoping to eek out a few more rwhp. What I ended up with was less hp and a terribly rich fuel curve! At this point my
rational is yank the intake spacer (possible air leak) put the heat shield
back on and things should return to normal. My tuner is not in agreement
with me and thinks another "power tune & reburn" may be necessary.
Unless I'm mistaken the programming in my chip is "static" and therefore
will not change by itself so if I replace all parameters to the original setup
(of the burn) shouldn't things return to "normal"?

I had the phenolic spacer on my GT and lost power. I removed it cleaned the MAF and now its back to normal. I would try that first. I was told by my tuner at www.jmschip.com that they have seen more too often those spacers causing a lose of HP and torque. They are not worth the headaches. BTW I lost .5 sec in the 1/8 with mine installed.

Yank the spacer, put the heat shield back on, and pull the 75mm throttle body. You should feel a huge difference.

I'd also lose the chip, yank the C&L, and get your tuner to do a good dyno tune on an autologic chip (a/f, timing, etc). That should make a difference as well. The C&L should be leaning you out, and making some power, but when it comes time to dyno tune I'd either run a stock MAF or a Pro-M.
