I don't see how this is possible, unless the turbo car had zero timing in it, was running at a 9:1 AFR, no intercooler, and a 2" downpipe.

 

Boost leak? The only think I can think of that would actually drain on the motor would be a big boost leak.

Do a pressure test on your ic piping.

 

car is at local tuner shop....... i manage a repair/tire shop

</TD></TR></TABLE>Whut....4psi of boost? Who the hell would boost that low wif a T3/T4 57 trim? And why would you slap a turbo on with that kind of compression ratio?! Sounds pointless to me.

yea but he still should have made more power. somethings not right.

 

what engine management?

 

that turbo doesnt even come alive till after 9-10psi.

 

Boost leak is the only thing I can think of also

 

aem ems

 

its broken

 

on my cams the adjustable cam gears are set @ 0 on the intake & 0 on the exhaust

where should they be for a turbo car
the cams that i am using are crower stage 2 (63402)

 

bump

 

too much overlap from the cams? CR is really high for a boost setup + everything the same = no change in tuning? then being that advanced for an n/a setup will mess you up when going turbo... danger!

 

thats weird.

sounds like somebody doesnt know how to build a turbo setup.

 

throw up your basemap

 

i used the same tuner for both the na setup & the current turbo setup

i made less power on the dyno with the turbo setup @4psi


today i reinstalled the 7psi spring in the wastegate and it feels healthier , but still needs to be tuned more

ems 1010 ver1.11

 

no base map? maybe your tune is too retarded to early, you using a linair or step retard?

 

any aem tuners in lower ny,Western ct or northern jersey

 

Sounds like horrible tuning. Any more info on the setup? a/f ration? base maps?...
BTW Take pictures when you pull shards of the pistons out of the pavement and hood.

da trooth

 

i personaly reinstalled the 7lb spring back into the wastegate, but i need tuning help

afr's 12.5 under boost

 

Try retarding the in-boost timing. When the mixture gets thicker it takes longer for the flame to spread.

Also, you may be misfiring. You should be using plugs a step colder than before and gapped at 0.030" or so.
