hi my last posting i had a problem with the car reving over 1500 rpms but now i finally figured that problem out. Now the car starts up no problem idles very smooth and revs up to 7 grand at an idle no problem. But when i went to take the car for a test drive when i go to get on the car boggs down after like 3 grand and when i shift to second same thing, it boggs out every gear. so now the car is running and has no problem reving at an idle but cannot drive it on the road. so can someone please help me out please i want to get my car on the road and drive it.

Do you have a front mount intercooler? if so check your couplers or anywhere for boost leak.

did you check by using a boost leak tester. because the slightest pinhole can cause problems. when i first did my swap, the ic piping i bought off ebay was cheap. it was cast aluminum, and by using a boost leak tester and soapy water i found several pinholes in pipes that had to be welded up.
