Have a 21GT 10R80 and soon adding a ESS G3. Curious if I should stick with my stock IM or run a boss? ported or non? I’ve talked to 7-8 guys at the track (drag strip) and read several threads who all run different manifolds with their setup and curious which is optimal? Thanks

My Steeda Drag Ultimate Stop the Hop kit along with the Adjustable differential bushing insert system came in and getting ready to be installed next week. Has anyone tried both the red and black inserts? If so did you notice a difference between the two. I do alot of roll racing and go to the...

Sorry for long post… I have a 21 GT 10R80 with 8,000 miles. Recently had the transmission fluid checked when getting the oil changed so that part is good. Hows everyone’s car downshift when driving in town or getting on it (driving more aggressively) and above 55-65mph and apply the break...

I like the sound of this set up but I’m actually going to switch out the cat back to the MBRP street version with 2 MBRP resonators. Hope this video helps anyone thinking of going this route. I will post another clip once I switch out to the street version.

Had kooks LTH green catted added to my 21 GT and picked up 17hp but gained zero torque? Also added a 87mm Ford performance TB. I was little taken back I didn’t gain any torque. Any input would be helpful. Thanks

I currently have a flex tune and each time I go from switching from 93 to E85, my car seems to do a few things it doesn’t while on 93. I literally runs perfect on 93 and when switching fuels, when I come to a stop the car idles down to around 500 and feels like it’s going to stall but never...
