what size tires are you running? i ran on some bigger tires (about 30.5-31ish) and in third gear it felt like the power wasn't there like it was with the 28''. my 60ft and 1/8 were about the same. but mph was down and 1/4 time was off .2
 
I Have Nitto 305 On Stock Rims Tire Pressure Was At 15psi I Was Getting Like 1.9 60 Foot My 1/8 Mile Time Is There But After That I Dont Know I Have Talked To Different Dyno Shops And They All Say Bad Things Bout The Place I Got Tuned From Said They Are Not Good With Lightnings So I Will See How Getting A Different Tune Does For Me And I Have The Stock Pos Air Tube I Heard The Airtube Accutally May Start Sucking Together During Acceleration But I Just Dont See How That Would Kill My Time As Much As It Did With The Numbers I Put Down
