I would ignore all and keep digging till you get there. When 1/8th improve so do 1/4 times. Any car I have been involved in usually has a second hidden in it from the first pass. You are right reading MPH and HP. Might be advance but might not. Might be gearing , tire size (running out of RPM before the traps. Maybe not but i would never sit back and say ok. Like the Ragu Spagetti sauce ad says , "Its in there." All ya gotta do is find it.

Hello Dolmetsch, Decided to change exhaust front to back and it worked, we had this stuff in stock. Found over four tenths here. That was under the meat balls, love spahget. My 60' slowed to 2.2? The 1/8 stayed at 10.0? and the 1/4 now 15.8 @ 84.3mph the car a put on 50lbs so the gain is almost 1/2 of a second from before. What will we do next? 3380lbs with me in it!!

Exhaust can definitely help. I just picked up about 2 tenths on my Slantkota and 3-400 RPM on the shift points with a better exh system.
