with an average of 13.1 afr at wot. i was very dissapointed, i wanted at least 350rwhp. we gained 24hp from the street tune to the dyno tune. they said the condition of the rear end was eatin up some horsepower. so steve is going to put 4.10s and a complete install kit from thunderracing in next thursday. for parts and labor hes gonna charge me $550. so i think that is a pretty good deal. i also found out the day before that my synchronizers are goin out in my tranny. so the beginning of the year i have to get that rebuilt. bye bye tax return. lol. i have the dyno sheet if yall wanna see it. and it was on a mustang dyno.
