On 87 i say zero..The gains are from more agressive timing aka 93 octane.
Ive seen 14+rwhp on a tunes with 93..

If you get a 93 tune get a dyno or road tune. The canned tunes are OK but you want every ounce you can get in your tune.
This really sucks.My car pings with 93 tune. i even tried to use the 87 tune and advance the timing 2degrees with my Xcal2 and car was also pingingwhite99gt said:
Something is goofy somewhere. Maybe the timing is advanced too much in the 93 tune? Who did you get it from? They may be able to help you out.Mustanggt108 said:This really sucks.My car pings with 93 tune. i even tried to use the 87 tune and advance the timing 2degrees with my Xcal2 and car was also pinging. The only thing that will work for me is 87 tune.So basically I gained completely NOTHING from my $399 (Xcal2) besides gear ratio
remember though, you might only gain a few ponies peak, but you will also gain a few ponies THROUGHOUT the whole rpm band. sometimes, its not always about peak power output.
are you running the 93 tune with 93oct gas right? its possible your gas station is using ****ty gas, and its not 93 octane it should be. ive used 91 at some places on my dsm and never had any knock/det, but some other places 91 and id get it till that tank of crap gas was used. im in cali, so 91 is all we get unless you go to "special" gas stations(ones truckers use have 100octane usually).
try the 93 tune and back down the timing a bit and add a wee bit of fuel in the mix and see how it goes. if it still pings, try the 91 tune(if there is one, i use diablo so i dont really know SCT stuff) or try a different gas stations gas. or maybe a little dyno time could figure things out, but itll cost a bit to get a tune and a a/f readout.

Holy crap four posts.
You will experience pinging if you advance the timing with 87 octane. You need higher octane gas to increase the timing. I didn't know places existed in the U.S. where you weren't allowed to have anything but 87 octane... some cars require higher from the factory!
Try this, do some math and get some octane booster to get your gas to 94 octane or so. Then try the tune. I don't know what this would accomplish if you can't buy 93 octane gas, but at least you can get the satisfaction that $400 did something ...

The supplies are hard to come by in some palces on the coast. There are still stations where I live that only have 87 some days.FalconGuy016 said:
Try adding some octane boost. Mine would ping sometimes with 93 and I'd add some octane boost and it helped.
