OK, so here's the deal...The facts:
2000 Lexus GS400
~97,000 mi.
3 yr old K&N FIPK (cleaned filter about 10 times so far) - perhaps ready to replace filter.2 yr old Borla exhaust (rear section only...for those who don't know
)
2 yr old Torque Master Spark plugs - perhaps ready to replace
---results from a 2 year old DynoDynamics Dynamometer---
The best dyno run (baseline) showed that I was around 250.8whp/278.2wtq
After the A/F tuning (only on WOT), the best post tune run yielded me 268.1whp/296.3wtq!
+17.3whp and +18.1wtq!!!
I can definitely feel the results and the Neo is cool, many display functions! I was hoping to hit 270whp...but I'm right there. Now, in the next 1-3 months I will add some S&S headers which will (hopefully as read on these forums) add another +18whp then after another re-tune of the Apexi Neo maybe an additional +3whp should land me right around 290whp...not sure what will happen to torque though. The car sounded AWESOME on the dyno in the shop. People were like "what the hell do you have in there?" and I was like "just an intake and exhaust." lol. Eventhough there were many cars (Evos, VR4 3000GT's etc) that were making 400+whp they respected my ride because they really haven't seen a GS on a dyno before and it sounded mean!
It was a cool experience...first time on a dyno.
The tuner only printed the dyno sheet at 3300rpms and up because the beginning of the chart looked messed up because he was trying to hold the gear and then hit WOT...plus me having a high stall TC also made things a little difficult for him. BTW, he did a lot of runs!!!
Below is a pic of the dyno but can't really make out the chart that well so I will scan a fresh copy on Monday when I get in to work.
