+1. You just won't see the crazy torque gain like on revups, making the dollar vs gain more of an issue. But I'm sure once everything else is opened up, the MREV2 can show more gains with a tune.

Looks like I could gain 2.5 HP. 5TQ. I installed the LIM gasket, so that would be essentially the same as replacing the LIM myself.

yeah, I was editing and adding to my list as I was going lol

Oh, and if the OP already has tp's or high flow cats the headers wont add much more power. Ideally, if you want to stay NA, but you don't want a fully built motor, but you still want power, go for NA cams. A new tune will be required though, and I have very little confidence in the osiris, so.......

I'd add headers and rear end gears. 4.08 gears make quite a difference on an NA VQ engine.

I waited until I built a new motor to add cams.

Why very little confidence in the Osiris? The dyno proved good numbers.

How much are gears usually?

You could also look into headers, which would help a lot especially if you went FI. A must if you wanna stay NA, you also could look into the mREV Lower Collector from Motordyne, that would help open up some extra low to mid end torque for ya. I'd say go utech or AAM for the tune

i would not switch to the utec from the reflash. why would you? Osiris can pretty much handle (everything with the exception of a few sensors/boost controller) and it has all those oher nice features. Plus you already paid for your license... get a vortech tuner kit and 550s/walbro and retune and call it a day

+1 on the vortech, it will complement your current mods nicely

I look at the UTEC as a fancy Piggy back, where the Osiris is an actual reflash. That's why I went with the Osiris.

Someone said with an SC that I wouldnt be able to tune everything with OSIRIS, and I would have to swtich to UTEC. Is this true?

not at all... osiris will be pefect for you with a superchager. Utec, while still pretty good wont be able to handle all the things as smoothly as the factory ecu can(as quickly either).

Also consider the fact that it will only cost you 300-400 to get reflashed
