recently had car dyno tuned and ended up with 424hp 382 tq.Auto with stall.Air temp was between 85-90 and humid.He mad about 6 or 7 pulls maybe.take a look at the graphs ,what do you think.Should i be happy or is there more power to be made?Not too many pulls were made because he had a problem with his chip burner so multiple changes were made per chip.AFR was 13.04.Look at max rpm.he said on another pull he took er to 6300 but no power gain,i dont think she ran outta steam that early but maybe.Pulls were made thru full exhaust with cai attatched.would of liked a pull with cutout but didnt get one.Take a look at mods in sig and what do you all think Is there more power left?Another tuner?Alvin did not do this tune he did the mail order that netted 411hp

For some reason car would run rich when went to closed loop so he did a open loop tune and disabled closed loop.I have been all over the car and do not see any type of exhaust leak anywhere which is what he said could be the problem,new delco o2s.everysingle part has 2000 miles maybe.i am 99 percent sure there is no mechanical problem.Could it be a bad computer causing it to do this?Is it okay to just keep the open loop tune or is this a bandaid for a problem or lack of knowledge of a 93 speed density car.Car runs well though,times next week hopefully.

Your converter is causing some horsepower loss. Also it looks like you tires are slipping on the dyno drum and maybe cost you some ponies.

 

To be able to make a pull that low in the rpm band his converter had to have been locked, aka no converter slip therefor no loss. Send you graphs out to Brian at PCM4Less and have him look at them, he needs to do a little more with your air:fuel. Get that worked out and your likely to see some more power. Your air:fuel is a little too much al over the place for my likings.


Numbers aren't quite as high as yours but look at my air:fuel.
