" Dear XtremeFI - received your LT1 52mm promptly and was impressed with the quality and workmanship. If that wasn't enough, I was very pleased after I installed to find much better low end punch and the car revs out harder. A 3rd gear scratch is now easy. Thanks" Ted Marsowicz

"Awesome product - couldn't believe how much low end rock crawling power this added to my TBI motor - and my truck idles great again. Horsepower is huge for powering through that thick mud. Please share this recommendation with any of your customers" Doug Wehrly
