KK well i recently put my turbo on and and running a 2 bar map sensor...ill goto do a run..and im fine all through first gear...then i hit 2nd or anyother gear and once i get up to around 5000 rpms it cuts out...like it wont let the boost go and just like pops and pops if i keep on the throttle to try and make it go...what could be causing this...could i have not setup the basemap right in crome? not enough fuel?...its really driving me nuts

 

are you sure its not a boost cut?

 

w.e pre gap is on ngk irdiums i bought them and pop them in...boost cut?

 

It's always a good idea to check the gap on spark plugs, even if they're pre-gapped.

 

could be running too rich

 

i dont think you can re-gap iridium plugs

 

don't use iridiums...^^^what he said. they're expensive and uneccessary. use ngk v power and gap them to 28 or 30.

post up your basemap so we can take a look at it. do you have a wideband on it or are you going to have someone else tune it? don't do any boost runs if you don't have a wideband until you can get it tuned.
