| Ultra's Dyno test II Exhaust |
Subject: Ultra's Dyno test II Exhaust by Ultraman on 2011/4/22 23:26:31 I took the 90 down to DynoSport today to see if we gained anything with the new exhaust system. Here are the results:   I was a little dissapointed in that I was thinking 220 or even a little better rwhp but we gained 17 hp and 16 tq which is ok through the stock mufflers. As you can see the AFR got a little fatter so it was running richer. So I don't know at this point if the EGR delete is doing that or if the new exhaust system is. The first run was the best and the other 3 were less by around 3 to 4 hp and less tq also. He thought the anti knock might be kicking in maybe, thus retarding the spark a bit, but I have yet to hear it ping in any gear at any rpm. The tuner said he could tune it to lean it out and shut off the ck engine light and change the fan temps etc for around 400 bucks including parts. Sounded a little high to me but I am new to the tuning deal. The car runs great and sounds good to me, even better with GT cranked up on the way home. |
