I'm using my 87mm TB still with my new custom tune. My tuner didn't have any issues with tuning the 87mm TB and I don't notice any drivability concerns while driving. Not sure why tuners aren't using the GT350 TB.People say FRPP tuning is very conservative tune yet it works with GT350 TB. I have 2015 GT PP car with Power Pack 2 I have looked at GT350 Manifold or 2018 Manifold. Every tuner I've talked too we can make more power over your current setup BUT say don't want tune with GT350 TB because at 2300 RPM you get a surge. Oh great buy another CAI so you can use stock GT TB. Amazing Ford Racing can make GT350 TB work. I have been talking to Tuners about using GT350 manifold or 2018 manifold. Then you hear cost of GT350 manifold over 1000 dollars DAH if you buy it from Ford Racing but at Ford dealer it 540 dollars or 344 for 2018 manifold. Now figure in cost of another CAI or go back to stock. I would like to use 2018 manifold but don't want to lose low side either. Most of the time we're street driving and in traffic. I've read post say oh you won't notice it and then turn around say I downshift more where before I didn't have too WOW. Seen Fords dyno sheets showing all 3 power packs but what do they look like with tuners play with them???? Would like to do long tube headers but with extreme Corsa catback have to change to sports mufflers.
