Hello all. It's been awhile since I've posted...been awhile since I've done anything car related actually. Darn that whole money and time thing. Any way, took my car to the dyno today just for shits and giggles. With the ATP Eliminator GT2871R, 3 inch exhaust, water-meth injection, 15 PSI, and Uni software, she put down 259.34 horses and 232 ft-lbs with a nice smooth curve on a dynojet (4th gear pulls). The place I went to had some problems with their tach signal so the torque figure is a little iffy and I can't give any good RPM specifics. A/F ratio was a little on the lean side to me...it hit 13:1 at about 5000RPM and didn't go much lower than that all the way to red line. What do you guys think, is that normal for Uni software? Again the tach signal was kinda in and out so still a little sketchy on the data. After I build the engine and go back, is their a better place to get a tach signal from? They were trying to use a wire that goes to cylinder 3 coil. Overall, not too bad for my first dyno experience. Thanks.

Nice to see you back here! Not to shabby for 15psi. I think the A/F is a little on the lean side as well. What kind of fuel pressure you running? What injectors?

too lean for sure. check your fuel pressure at WOT, and do you have the appropriate sized MAF housing? |

I'll check it when I get some tools. I have a 3" MAF housing.
