WHo has 300whp and what do you have

Is that the Amuse ECU? Isn't that just a straight replacement of the factory ecu? UpRev is popular since it can be tuned with each modification as you go. It's most cost effective to save until the end once all the breather mods are done.

The VVEL code tuning will be the biggest breathrough in terms of ECU tuning and how much power can be gained. The UpRev really just smooths out the AFR and maybe plays with the timing a little. And of course, manages boost in FI applications. It's definitely nice to have once you have done full intake and exhaust mods.
