“I'm new to the tuner layout but this was easy enough to figure out. The tune from tsp that came with it is the only tune I'm running because damnit it makes it feel like a whole different car. Cant wait to do intake and full exhaust tune it out some more. By far the best purchase I will make for my 18 civic si bar none.”
“After a lot of research I finally pulled the trigger on the prl CAI and Ktuner. The process was smooth and being able to track my packages was great. I will be buying more products from two step performance in the near future. Thanks”
“Great customer service with fast shipping .One of the best mod that I ever bought for car. The base maps was freakin cool but when I receive my stage 1 tune it really boost up my car gave so much power I didn't expect to. Can't wait to get a race maf housing and race file tune for my car.”
