If I look at the ESS homepage and compare 35i vs 35is tune, the 35is gets a lot more torque from their tune. 355 of torque on wheels for the 35i at stage2 and 407 for the 35is at stage1.
I thought the engines was the same? Can a 35i use the 35is tune?
Stage1 tune for 35is
Stage2 tune for 35i

Like the above said but you also got to remember that just because this one dyno gave these results, you can't compare them to a different car per sey. I'll explain my point by using the E92 M3 that I use to own. I got a wheel hp result of 360 stock and about 278lb torque but another E92 M3 (same dyno on same day) got about 325 whp and I forget his torque but it was much lower than mine. Both cars were the same engine and same year at about the same temperature. He was pretty bummed.
So much variation between the same model car, I would think the variation would be even more between 35i and 35is. It wouldn't surprise me to see some 35i pull better than some 35is stock even though that is unlikely. I'm just saying, the only dyno results I can compare are the same dynos for the same car after mods are put in. Between cars, there is just too much variation to base a decision on.
