1999 Z28 (mods in sig) Also the car was very lean for some odd reason so there are a few test pulls and one pull to 6000 rpm. You all know that my cam can pull to 6500 and then some but the fuel was not there. Also had a wierd miss as the shop told me and the passenger 02 sensor was not working. With all the stuff that was messed up, car made 403.7 RWHP and 364 tq. Kinda wish it made more but I'm on a TSP mail order tune at the moment and have some small issues to work out. Stock maf and throttle body also. What do you think??????

Vid is kinda long, but it was the first time ever at a dyno, so i went overkill.

my air/fuel went from 15.5 at 5100 rpm to 20.2 at 5400 rpm. I quit driving the car until I figure this out.
knock retard - 1.2 to 5.6 at WOT
timing - 38 to 28 at WOT
Pulse width of injectors - 12.5 to 17.2 at WOT

Also I forgot the Graph at his shop, but I'm picking it up Monday and I will post that also. The graph is missing some info in the upper rpm, line dissapears then comes back, he told me that was the car miss firing?????

Let me know what's going on.

Stock injectors and fuel pump. Fuel pump is ready to go, came in a day after the dyno. but what about injectors, you think stock should be all right, and what about 2002 injectors (28 lb) Would that be alright. I have plans on spraying this car (100 to 150 shot) Or should I go like 32 lb.
