my car is losing power when i shift to 4 gear but is for 1 second then
start to spin the tires again. It's like a instant drop of power, she is tuned and
nothing was touch. Maybe my intercooler is to small 28x7x2.5? The clutch is not sliping.

engine management? Had this problem

 

Same thing happend to me today
I had a clamp loose on the charge pipe
Would build boost fine and hold it
Drop when I shifted and then build slowly for a second and then fast again
Check all the clamps out

 

i use crome pro

V8 good advise i will check all the couplings and clamps.

 

What map sensor?

 

omni 3 bar

 

You always go for the map sensor being bad.... that's not always the problem so shut the **** up

 

reajust all the t-bolts and check the couplings all loock fine. Can't check the
car cause it's raining so heavy.
