I went to Milan to do some test n tune because my car felt weak at higher rpm and I am trying to dial in the right settings but I am totally lost on the way my car runs.
I don't get it, somebody help me out here. With 76/86 jets it ran way too lean and bested a mph of 109, with 80/90 jets it ran better, with 84/94 it ran 111 mph and with 88/98 jets which I thought would be a huge overkill it ran the exact same 111 mph. I used the 88/98 jets and it didn't even run rich!!!!!! It didn't bog off idle or show any sign of black smoke. It ran the exact same as it did with the 84/94 jets. 4 runs in a row with jetting between 84/94 and 88/98 were all 12.7 @ 111 mph and all were with a 2.1x 60' time. With these jets it should be running pig rich and bellowing black smoke, I don't get it! It feels weak at higher rpm and the only thing I can think of is that my fuel pressure must be dropping or something except for the fact that it doesn't run rich when I first take off.
Any advice or ideas????????????????????

 

you could always take it to these guys for a dyno tuning session.

that way it'll be the best it can be and you can watch the fuel press. during the run. you can also borrow my fuel press. gauge/line so you can watch the fuel press. as your driving.
