Heres an easy boost level on 93 oct. Im running speed density too. my tires are 205/55/17 studded. Excellent for winter fun in the tug hill plateau.

This has been a 430-440 hp car my entire time tuning, learning to tune cams etc, WOT was always easy but now Im finally getting the hang of transient throttle tuning with cams. Good learning experience, and hell,, i didnt blow it up!!!

boost creeps because Ive got the FP 25psi wga preloaded a couple turns and this is where it lands. looks like 22ish. No boost controller hooked up, this is straight reference line to the wastegate.

 

very nice

 

this is very similar to the setup im am building. plz post up all your mods.

 

Mods are listed in the title..71hta turbo, skunk2 intake manifold, gsc s2 cams, 3" exhaust, and o2 dump

Are you planning on upping the boost once your back on non-winter tires? I'm curious as to what it would make in the upper 20's

 

Stock FMIC?

This turbo is awesome and relatively cheap.

 

Mod list:

71 hta
S2 cams
Skunk 2 by STM ported mani
Stock exhaust manifold
Muse o2 dump
Jmfab Garrett core 3.8 ic
Buschur dp
Sport exhaust hks
STM uicp
Greddy type s
Fb70 mm tb

 

Same peak power with much more tq on a mbc. I'm not gonna force much more boost up top but. I've let her have 30 and it pretty much makes 410 +- tq tapering fast

 

vouch for the WG thats pretty much what mine was doing with the same WG setup 19-20 tapering to 22-23lbs. on random it would go as high as 27lbs but it was weird, would do it only every few runs. tightened it another turn and would hold 24lbs pretty well to 26ish.

 

I'm swapping on a 3 port ASAP so I can do per gear

 

yup already did now im getting 33-34psi tapering to 29-30.
i have it set for 70 wastegate duty and my logs show its doing 60, cant figure out what is causing the difference so when you get yours let me know how that goes.

 

there is a few mods left out. what ic pipes, what intercooler, throttle body. So if you dont know, keep ur trap shut.

 

MAF compesations for baro/temp.

 

lol, i listed the major stuff that changes power..

waiting for the guys to say a 70mm tb is 16 hp and a short route UICP spools quicker!

The intercooler.. yeah did forget that!

Im planning to get a CBRE extreme port stocker when my state tax refund comes around.

 

looking good! worlds longest tune though LOL! a tune that never ends! the luxury of being a self tuner

 

For sure I'm stubborn !

Spent a lot of time messing with the stock ecu als and while I did make it work I wasted valuable tuning time .. I'm still on sd 2.0 88587614
