We have been running the KB on our 01 Lightning all summer. making it the worlds quickest and fastest gen 2 with no other power adders! we have run a 10.82@124 with a 1.49 60 ft.(soon to be 10.50) with a 4,300+ *truck*.. we made upwards of 250 h.p. with the KB unit. We will be bolting on a KB here very shortly on our 03 cobra which has already went 11.2@123 (WITH THE STOCK sc & on bfg's! I'm pretty sure we will be running in the 9's with the KB..$4,000 = 9's i'd say its well worth the $$.remember keep the boost levels at a respectable level 15-19# and pump gas will not be no problem!(with the right tuned chip) at those boost levels with the KB the average cobra will be running 10's all day long!
