Hey Shiv, I have your xflash on my evo and I love it. I have a question for you.

You tuned my evo and two of my friends Evo's. Mine whp was 30 less then both of them and we had the same upgrades. I was curious, I put my cat-delete pipe on the night before and by the time I had mine re-flashed , my CEL was on. THey changed there delete pipes that day and had no CEL.

"Can a CEL throw a car's HP off by 30whp just by having a CEL on. can a CEL deceive the car's performance and make it run differently?"

Any answers on this would be helpful, and I will take any and all suggestions. If anyone other than Shiv can answer this, I am open for suggestions and am all ears.

We are still trying to figure out why there was such a large discrepency in whp.

Thanks again Shiv for the tuning. I love it and would not change a thing.

P.S. If I changed by intake back to the stock box, would I need a reflash?


Thanks

Smokey
