I have a great new tuner! I will keep that confidential at this time. So I ran with farm truck and arm. Got my younger 15.5 yr old daughter a slug bug shirt which they both signed. Now the run that got me kicked out.
1). At 5400 feet I ran 9.71 at 142. There was no other car or truck as fast as me. There was a towed ninja bike which ran 9.71 at 138.
I got a 1.35 sixty foot.
2). My tuner read some logs. With a 10 percent lower and 2.5 upper I was only making 14 psi. The sc is original and probably worn out. He said the kpa was only 200 whatever that means.
3). So he is having me add one degree of timing. But I am going on vacation and can’t log for him for two weeks.
I think I may keep it Mopar and go with a 2.7 and a ported top.
I am sure I could of done a 9.6 as when I ran at 5 it was 83 and it cooled down to the high 60s. Just weird only 14 psi.

Local tuner or bigger name? Jon data logged my stock car last weekend and I thought he said he saw 11.8. DA was around 0. Now keep in mind, with higher DA you loose boost being there isn't as much air to compress
Also the bigger cube engine is going to flow more air which will make the boost drop. Boost is back pressure so for instance if you put a 2" exhaust on your car boost numbers would go up but it also would probably be slower

My youngest daughter, 15.5 yrs. old had taken this. Not too good. But she was a sweetie even wanting to go with Dad to the track. My older one, 17.5 yrs. old will not even consider going.
