Car seems to pull good thur the quarter mile but leaving some on the table as it takes time to pull back up in the power band. Any Ideas?
Can you give us more details, such as what convertor did you use when the 60fts were 1.30, why did you change convertors, what did you use before and after for convertors. What kind of RPM range are you running in before and after convertor changes? Are you using a FAST and do you have any logs? Thats it for now, but more info is definitely needed... oh ya, who am I speaking to...
