JLT & 2010 GTs
Saw this and thought it may interest some of you. Directly from JLT...
" Rumors been that the 2010 GT doesn’t respond to mods like the 2005-2009’s did and this had us worried. With Ford putting factory versions of Cold Air Intakes on stock new Mustangs what would this do to JLT Performance?
Well, what we learned was not to believe the rumor mill.
We got a customer with a Bright Grabber Blue 2010 GT and he was willing to be our test car. We jumped on it and got to work. The stock intake system is impressive, with a large Mass Air Flow meter, smooth intake tube and ram air tubing from the grille.
With the large MAF we had to go even bigger, much bigger to make the gains needed to warrant customers plunking down the coin for an intake and tuner package. Yes, this as with all 2005-up Mustangs requires a tune to keep the car running safe and make power.
We started with a couple of base line pulls to see what we were working with and the car responded with a 258.45 RWHP and 279.09 RWTQ at a lean 13.0- 13.3 Air Fuel reading from the factory.
We swapped the intake for the new larger JLT CAI and began to make the tune. A few runs on the dyno to get the tune dialed in and we were in luck. Bam, 284.65 RWHP and 308.53 RWTQ, that’s peak gains of 26.2 RWHP and almost 30 RWTQ. Even higher gains of 34 RWTQ between 4-4500 rpm and 26-30 RWHP from 5000 and up. This was on a mild 91 octane fuel tune, add 93 and I’m sure 30 RWHP is possible. We even made this power at a much safer 12.5 Air Fuel reading, so you have more power and are getting it safer.
Parts are in production as we speak and we hope to have packages ready in the next month or so. Any questions feel free to call. Prices have not been set at this time.
We will be offering a painted plastic version as well as a Carbon Fiber version.
We are working on using this larger intake on big HP 2005-2009 GT's as well. So keep an eye out for those test results. "

Exciting...but only if its true. Seems that the starting point is way off in the JLT example.
Another 2010 GT owner (stock) just posted that the dyno said 279 rwhp (inline with another posting of 275 rwhp)....
So...284 is way less exciting if the starting point is truly 279 or 275?
Wondering if anyone else has a good baseline for rwhp on 2010 GT Stock?
