Took out 305 TPI and put 350 TPI in and car won't rev over 3k rpms. I have the stock 305 computer, sensors, and chip but have done a lot of work to the 350 (Cam, injectors, afpr, headers, accel coil, pulleys...) The car starts and idles great but acts like its not getting enough spark when its revved up. PLEASE HELP

Hey,

Well what do the plugs look like and when was the last time it had a tune up

 

Are you still using the 305 tpi chip??
