joeflexromine

I have a sandrail that has a 1.9 efi in it the whole thing is custom. Diamond pistons .. crowder rods, it has a FAST computer in it forged crank and the head has all been gone threw to hold the power of a small turbo 8 - 10 lb of boost . it also has a inner cooler.

THE PROBLEM AND QUESTION 1 : I have completed the project it runs fine when ideling and at high RPM's AT IDEL. but if you drive it down the road and you floor it at about 4200 RMP's it back fires and wants to bog down.

I have look for vaccums leaks and the pipeing on the innercooler is all hard pipe nothing is colapsing under the boost..

I have not had this thing tuned yet but the tune on it right now is good enough for it to run and drive

any suggestions

the motor would be in a 88 ford escort
