So yeah... I got a cheap $20 deal for a few baseline pulls. no tuning no nothing. I just wanted to get an idea of how much power I was looking at.

well i came up with this:


This is also uncorrected, and at 5000 feet of altitude, so I think with corrections it would be higher, but thats not my concern.

Here is my setup:

D16y8 with stock internals
Garret T3 .42/.48
DSM 450's
Walbro 255 lph
Running uberdata
log manifold, tial external gate merged into exhaust
2.5" dp to 2.25" full exhaust. No cat.
audi 5000 intercooler, 2" charge piping.
running 7-8 psi with an MBC


OK, so i have no idea why the heck my power starts to drop off at 5500, that just doesnt seem right. Based on my torque value (about 160) it seems that i have a lot of potential because there is a lot of torque there. But the HP peak seems really low, the torque peak seems about right. I am running rich, but I didnt think it was that rich, although up top my car was spewing out some brown gas smoke.

Is my richness up top killing it? or is it more likely my exhaust? I dont really care too much that he didnt rev it out all the way, it was obvious the power band was done with.

I am running about 0.8 degrees retard per lb of boost.

any experienced tuners out there who can help me interpreting this and what i need to do next?

is vtec engaging

 

thats what i'm thinking now.... i wonder why the heck it wouldnt be engaging!!?!?!

 

do you know which basemap you are running? It might not engage vtec and be very conservative on timing and fuel in the top end. JMO

 

what kinda you are running? It might not engage vtec , check that out first that could be problem saying runing rich , is the idle ok thats another thing i can think of if there is something wrong in the basemap and not have vtec hit
