Here is one of my graphs from the last time I had the car tuned by Kasey of MAP. The first go around I had a Greddy RS bov installed and it could not hold boost( set to spike 25 settle around 22) so I purchased a ix DV and that solved the issue. The mods are Perrin dp, ix DV, MBC, Apexi open eliment filter, and a custom exhaust to a Greddy Evo 2 muffler. This was the only graph I ended up getting that day, but we ended up with the numbers in my signature. The temperatures that day were very hot, and Kasey did the final re-tune with only three pulls ( all I could afford that day lol). I;m pretty sure the tune can be smoothed out...but I am no expert. Kasey did the best he could with the time and money! I ran an 8.332 shortly after, but I feel like the car has more, that its my problem with the time, or maybe the stock clutch?

Absolutly. With the stock boost solinoid I maxed a spike of 17 psi, settling at 14 by red line...which is terrible. After the initial tune, with my MBC turned all the way up, the most power I could make was 280 ish wheel, but it was a huge power and torque spike. My boost pressure was spiking at a max of 24 psi, and by redline I was sitting at 16 psi. Imediatly after I switched bov's, I saw a boost pressure of 30 psi, and hit fuel cut. Backed the boost back down, and had it re-tuned, and now sit something like you see it.Originally Posted by Sixth_Vang
Was that BOV that bad?

Congrats on the new times at the track. Maybe we can get you a set of cams and turbo before I come back to NC.

I sold my friend a brand new rs bov and a few weeks later it started to leak. Now he's trying to buy a forge
Yeah, until the Evo, on my SR20det swapped 240sx I ran a Greddy type s. I was very pleased this that BOV.

Nice numbers. I guess I must have a awesome greddy rs running 30+ psi on hta35r and no problems.
Thanks guys. Kasey is awesome, and really knows what he is doing, he deserves all the credit!
