15.1 for my mods sound ok?

[logans dad]

Ran 18 pounds of boost on t-25 with 110 octane and gauge stayed real steady on 18 lbs all thru 1/4. when i got home put in 92 octane and at 18 lbs gauge was wiggling a little so went back to 16 lbs. I know this is a lot of boost but I started the night with 15 lbs and only ran 15.4. got faster as i turned it up and logger looked good.My vacuum at Idle is only 12 tho. why doesn't my boost drop as rpm goes up? I also still have stock exhaust with cat cleaned out and 4 inch muffler. I thought with my mods I might run faster.raced 2 srt-4s and I smoke them 3/4 of the 1/4 mile then just before traps they go flying by.Ive checked for boost leaks and dint have any. could turbo just be worn out?

i ran a 15.8 @ 89mph and this was about 2 weeks ago at mitsubishi day in about 95-100 degree heat, i only have a gst w/ intake, and exhaust right now, does that sound about right to everyone?

I was going to go to the DSM shootout but my brother and our friend got swept away by a 91 vr4 for 1,000
