Weight reduction on rotational mass results in less parasitic loss,
meaning you are not making more power, but you are putting more of the power you do make down to the wheels, IE more usable power.
The vibrants brought it down quite a bit but more importantly killed the trumpety tone that the combination caused. I ultimately cut off the Corsas and vibrants as the low and mid rpms was too quiet. I added the AWE Touring read section. Had more character in the low rpms and still screamed up...
The vibrants do a good job cleaning up the tone and bringing down the volume just a tad.
Back when I was full Corsa Xtremes and added long tubes the 3" version really did a good job of killing the trumpety tone that it took on after the lth.
Yup this. As was said very early on the very first thing would be to ditch the canned tune on the device and go with a real tune from a reputable tuner. The device should be used as a tool to load up custom tunes, not for the tunes that come on it. Then, tune for e85 if available in your area...
And runs much cooler! Even if only getting e54 like some flex pumps that is a significant difference in power and cooling, but definitely a decrease in mpg to go with the cheaper gas price as well so it ends up being almost a wash for that.
Ditch the Bama canned tune, but can use the device itself to load a custom tune from a reputable tuner. Specifically tune for e85/flex if available in your area. Add long tubes at the same time you go e. Then look at rotational weight reduction like lighter wheels, brakes, drive shaft etc. Then...
Claiming 65whp from intake and a Bama canned tune? Would love to see the before and after dyno on that as that would be the best canned Bama tune in history.
Pull carbon trap from intake to regain the 10hp lost. Or swap to the older MY lid as suggested. Either should reclaim those few lost hp.
That said, if you opt for any actual mods the warranty would not be voided but they can attempt to deny a claim for warranty work if they contribute whatever...
That's not even that bad on full e85. I'll barely get more tha that even running e54 (flex fuel bs). Track/fun days on e90 are a tad less than that too.
You're going to want something that won't drone and cleans up the sound. Corsa Sport sounds great on long tubes as does Borla S type or AWE Touring. Should bring volume down and refine the sound alot.
You're also going to over pay on AM for most things and not get the level of customer service...
