I put down 370rwhp last night with procharger installed with 90mm LMAF but it pegged out at 4000-4500 rpm. So... I'll be picking up a sct maf. Perky at BBR (Booze Brothers Racing) tuned it for me and did a great job. I just wished they had a SCT MAF in stock because he was 100% sure we could of got more out of her. We ran it with stock MAF and got 330rwhp and then installed and tuned 90mm LMAF and it jumped to 370rwhp. (good times!!!!)
