I know, I’m just saying these 700 plus whp claims are just that, claims. It just so happens that a single walbro on race gas is tapped a round 500-540whp and 1600’s on E85 are tapped around 600whp. Kurts car dynoed 690, or about 100-190 whp too high and this most recent evo is a MIMIMUM of 100-110 whp to high.

The J&S dyno is at least 100whp high but could be up to 150-200whp too high depending on the car. That is a significant value.

What is odd is that some cars read “normal” while others do not. Even more so is the lack of dyno sheets posted by J&S themselves. It seems to me they are inflating numbers of cars they have tuned/worked on or have a vested interest in.
