I was wondering I'd someone could shed some light, car is on the dyno and hptuners is open, at 6k rpm the car leans out and falls on its ass, guy tuning says the maf sensor isn't reading past 10k htz but it goes up to 11,100k htz

 

Should have posted this in the tuning section. Maybe area can chime in on this for you. Get am mod to move it. Thanks

 

What pulley, fuel and injectors

 

Ok, hopefully mod will move it, and zzp's 80lbs injectors 2.6 pulley

 

On dino fuel?

 

No premium n it's only making 270hp and 240 trq

 

What brand dyno?

 

Dyno Jet if I'm not mistaken, we got the MAF issue figured out and it runs smoothly I'm just disappointed with the power.

 

What was wrong with the maf

 

Wat r u iat2 temps

 

It wasn't reading properly so after 6k it would rich out and drop hp almost to 100hp but he figured it out, it was something in the tune.

IATs post charger are 131 and are pretty constant

 

Are you pushing enough timing?

 

Well in diag he can up the hertz to be maxed around 16k. Now if the car leans out and he's going based off afr error add fuel. It is honestly not difficult but in wot your feeling is based off your prest calculated fueling so if it goes lean then he needs to up the calibrations.

 

270 is good for 93 gas only, if u want more gonna need meth or e85.

 

or raise the pulley up

 

just under 289 and 260 tq on mine......that was with stock exhaust and no cooling mods.....it opened up a LOT more after the 3" exhaust and some cooling mods.

 

Something is off, I have ZZP Long Tube Headers and DP, Option B, Dual Pass, Secondary HE, 80# Injectors, 2.6 Pulley, 3" intake so what am I missing other than maybe an LS4 TB

 

oh, an that was one a 2.9" pulley

 

I think you may be missing a good tuner

 

 

what plug and gap are you running?

 

Stage 2 colder plugs ngks gapped at .30

 

it's hard to say without seeing a datalog and the tune......but it's possible it could be spark blow out....maybe try tightening up the gap just a little more.

 

Do I need to upgrade my MAF sensor?

 

doubt it......but it is hard to say what is going on without seeing some data
