XE230/236 114LSA Dyno numbers
Well, the car felt soggy down low and I knew it. I was running my previous tune from last year (which had an A/F of 12.2-13.0).
My first run (fuel psi @ 55) I pulled 368rwhp and 335rwtq. That is a 17rwhp and -5rwtq gain from the homeported heads and shorties. Here is the kicker, my A/F with old program was 10.0 across the board this time! It was off the chart!
I was using datamaster to record data. I was running 42 degrees spark advance. I decided to adjust the AFPR despite what everyone says about the computer controlling the A/F.
I ended up getting the A/F to 12.5-13.0 and cranked the numbers up to 384rwhp and 350rwtq. I ended up tweaking alittle more and got 383rwhp and 353rwtq.
Here is the kicker. I picked up 100 rpm in hp (peaked at 6k compared to 5900rpm before) and the peak torque peaked at 5400rpm instead of 4800rpm before! The torque curve is flat and fat. I have 343rwtq from 4300-5800rpm, and at 6k I still have 335rwtq! I have 300rwtq @ 2400rpm and it slowly climbs. All in all I picked up 17rwhp and 18rwtq peak over the first pull just by playing with A/F.
So, final numbers are 383rwhp @ 6000rpm/353rwtq @ 5400rpm.

So tell me how badly did your HP numbers dropped after 6k? What were you making at 6500+ rpm?

The port job I got from Lloyd (nighttrain66@msn.com) should cost well under 1000 bucks. I dont know how much his prices are now, but around 700 should be close. Best bang for the buck head.
