Finally installed the Gen V and Northstar throttle body, Tune Time Performance tomorrow.

Yummy.

That looks good.

So clean. Much respect. Kinda weird seeing everything backwards. Different perspective, I suppose.

Wish I hadn't sold my '86 GT, stupid HOA. That thing is clean as hell, good job.

**SnowTh1ef** · 02-23-2015

So beautiful!!

Gorgeous car. Wish our '87 GT was half this pretty!

Dyno tune with the Gen V and N*, they call the Mustang dyno the heartbreaker now I know why lol

I think that's about it, maybe I forgot something.

Edit to add, Green Giant 42.5 injectors.

I just upgraded to a DW300 fuel pump, 320lph. Now I'm second guessing my 42.5 green giant injectors? I've done a bit of reading and still undecided, any suggestions?

It's getting faster, still should be doing much better. I'm having an issue with the auto trans over revving the 1-2 and 2-3 shifts.

this is so badass. My buddy has two fastbacks an 86 auto and an 87 getrag . he has an l67 to put in the 87 but has lost time due to kids and such. He does have a l67 swapped 90 lumina though.

**JCircs** · 04-16-2015

I want 11's bad!!!! The transmission isn't shifting for some reason, you can see in the video it's revving to 6500 rpms. The cam/springs max at 6300 and on the dyno it looks like power is only made up to 6k but regardless of the PCM shift points it just won't shift!!!

**TexasTanker19kilo20** · 04-17-2015

Clean ride.

**JCircs** · 04-19-2015

Thanks again for all the compliments guys. In an attempt to fix the slow shifting/over revving auto trans I ordered the Intense shift kit, if that doesn't fix the issue I'm going to need to start shopping for a built transmission.
