Dyno Tune After Trifecta Tune
Got my car dyno tuned today at IPS Motorsports in Columbus OH.
The car previously had a tune from Trifecta on it.
The first pull the car produced about 307whp.
The tuner said the car was running lean and getting some knocking in the upper rpm's. One of my o2's is reading on the lean side at idle, and im getting low voltage to my pcm. About 11.5 volts he said. Maybe a bad ground i'll have to look at it. He said the car was pulling a bunch of timing up top.
Anyway, he did his thing and i ended up with 335whp and 340wtq.
Can't wait to get it back to the track!
I got a pic of the graph and a cell phone vid for you guys.
The motor is a 355 LT1 with the hot cam, ported heads and supporting mods.
