boost question w/ tst

[cclark746]

alone with the p0341,an p0336 codes with my tst even on say 6/6/2 at wot my boost will fly up to 35-38 and with it still floored it falls quite abit and i am getting rather toasty egt's i have the boost elbow from edge installed.

Is this normal the fall in boost at wot are should i change the elbow?? Are yall's EGT's Toasty even on 6/6 and lower?? 6/6/2 i have to let the throttle because the Egt's are 1350+

With the stock turbo you reach the peak boost and then it will drop from there as the air temp going thru the turbo/intercooler continues to climb as you pass the top of the efficiency curve on the stock turbo.

When I had a stock turbo and stock injectors I couldn't keep temps reasonable at any setting over 5/5 (non-adjustable timeing version). I think you have just maxed out your stock turbo.

i have the adjustable timing on mine but i just alil confused you look at tst website and show lever 9/9 and 200hp and 600tq gain w/ stock exhaust and air filter only added a pusher pump and clutch my truck with stock turbo will never be able to see 9/9 under hard acceleration is this the case with everyone

I can hit 50 psi and 1500+ on 6/6 so I dont go there very often.

Level 4/4 keeps temps in check and boost is simular to what your seeing.

It's normal to see boost spike and then drop slightly to whatever the wastegate is set at.

i think so that is what i was trying to find out. but i think it is normal. but i do have a problem with tst making that much hp on 9/9 and i cannot even get mine over 6/7/2 and i know i am not making 600TQ so how in the heck did tst not damage everything on the motor when they turned it on 9/9 with stock exhaust and stock turbo my motor would melt down!!!!

Same deal here with not being able to come Close to running 9/9 on my TSTwhich has pressure. I have 4 " mbrp, glacier fuel system, and drilled stock air box. i can go 6/5/3 but it will surge on the top end and get real hot if i go any higher. I want to know how they got 200hp-600tq with only a pusher pump ?

My guess is either you are outside the turbo efficiency map, or you are draining the rail pressure down and egts are increasing due to lack of atomization.
