I've been rolling around with XCal2 for a couple days now and here are the observations I have made with both files Perf1 +2 and Perf1 +4. I'm waiting for feedback from Torrie, but I just wanna know if what I am experiencing is both "normal" and/or adjustable.
Pros:
- No ping at all thus far, regardless of tune.
- In D4/D5 I spin much harder off the line than I did before.
- I kept up in the 1/4 mile (using auto-stick and shifting right at about 6200 rpms) with my buddies '89 foxbody 'stang with headers, intake, and exhaust. I didn't get a chance to run him in D4 or D5 but I can't imagine being able to run much faster than I did.
- When I use the auto-stick and downshift into say 2nd from a 45-50 mph roll and floor it I get awesome throttle response and a noticeable difference in acceleration...
- The shifts are smooth when driving normal
Cons:
- In D4/D5 OR when using auto-stick at WOT the shifts are much harder, almost no matter where the car shifts at. And I mean MUCH harder, almost to the point that I worry if this is going to cause trannie damage...What can I do to adjust this? Did anyone else have this problem with their tunes?
- My MPG went from around 16.0 to 12.7 in one day (this may have been caused by my "experimenting" with the tunes but also due to adjustments to a/f ratios)
- My car accelerates very slow from a roll in almost every gear, in fact MUCH slower than it did pre-flasher. If I just hit the gas at about 2-3k rpms it hardly "lunges" forward, even with the perf1 +4 tune. It isn't until after 4000 rpms that the power really kicks in. As with the shifting I have the same questions. Can I adjust this? Did anyone else have this problem with their tunes?
Like I said, I'm waiting on a response from Torrie, I just thought I'd ask you guys as well...
