It has very good throttle response in the free rev like sitting in the driveway not driving. It's bing bing bing right there... It's the under power when it shows the worst. let's say I'm in 3rd gear and I slow down for a heavy curve in the highway and I get around the curve and I'm down to about two grand and 3rd and I just stab it it falls on its face and then takes off.. or if I'm cruising at a little bit higher RPM at about 25 to 3 Grand and stab it it sputters and goes... If I roll into it a little easier or just flat get on it, it gets down and goes.. the a/f gauge shows 13.2 or so at Idol and gets down into the 11 and 10 at Cruise but pops back up to about a 12-1 with the air doors not really opening all the way at wide open throttle...
