got tuned again today and im at 250 whp yay...it ran great on the dyno and im driving it home and it starts bogging down when i hit around 2psi of boost? wtf? ne ideas?

 

what does ur a/f look like, does it bog past 2psi, or does it not get past 2 psi? you might have a boost leak

 

why would if run fine on the dyno though and then not good when its off it

 

I've blown couplers off before. Make sure all your clamps are tight and the couplers are on the tubing enough to get a good seal.

 

did they put a fresh set of spark plugs in the last couple pulls?

 

2psi at full throttle or just 2psi at like half throttle or so. Does it pick up again after it bogs or does it just bog and then **** out completely?

Also, is it a MISFIRE or is it a bog. Bog tells me that either your tuner took out a ton of timing at that portion of the map or it's overly rich. Misfire could be the spark plugs, ignitor, coil, etc, but if it's a misfire it's probably going to happen all over in boost.

 

its at full throttle when it gets up to about to psi it starts to bog and dosent get past it i let off the gas and just drove underboost till i got home ill check the couplers

 

Probably a boost leak then.
