Do it, really makes’um even more fun. My mods almost exactly the same as TheRedKey’s but doing intake plate port gained another about 50hp. Here’s the before and after dyno pulls, the 2 855 HP pulls pencil’d right over the top of one another, Cars VERY consistent and predictable.It’s just insane to me how much power these cars make with just a pulley tune and injectors. I’ve been avoiding doing this because don’t want to void the warranty or have to replace the blower etc down the road but man this has me thinking about just pulling the trigger.

744hp @5800 rpm, 739tq @ 4450 on dynocom dyno. Unfortunately I never had a baseline. Good/Bad/Average? Thanks.
The issue you for me is I have no one to do the work where I’m at and I’m not that skilled! That’s why I would probably do Barth as they are close. And the clutched pulley would be a must.If good e85 is in your neck of the woods give Mike at OST or Curt Dusterhoff a call and go that route or better yet one of their flex tunes. If I was to be able to do this again with what’s known now I’d go that route right out if the gate but with a 2.72 Litens pulley. If your worried about your blower go with a genuine Litens clutched pulley not a solid one and you’ll be good for a long while.
That’s not a bad route either if you can’t do it yourself and remote tune.The issue you for me is I have no one to do the work where I’m at and I’m not that skilled! That’s why I would probably do Barth as they are close. And the clutched pulley would be a must.

Mods and car info in signature. Temp was 76. uncorrected.Need more variables revealed. Ambient temps, are those corrected or uncorrected #s, car yr, cai, other mods... my signature has my results with a 2.85 and supporting mods on 93. Ambient temps were high that day too.
Yeah.. i had always heard that they produce power way up high and was thinking the same. Looked liked I was getting about 16psi out of upper only. I was on 14.5 degrees of timing for that as well.Good luck, Interested to know Tuners response. Your TQ figures look GREAT, HP just seems to fall off way too early.
