I did both factory setting and max setting with e25-e30 and I found that factory setting felt the best in terms of smooth power delivery and butt dyno.
Edit: @ColonelAdama is a Gem in our JB4 Supra community! In 2 days he looked at 5 different logs with 26 different pulls. We've got to the point relative to the JB+ the power is now up to redline, with no more choppy throttle and a smooth power delivery with a decent feeling on the booty dyno...
$175 Shipped in the US
Best Bang for the buck Mod, super easy install and Instant proven whp/wtq with the factory settings. Selling because I graduated to JB4.
Just bought a used JB4 from FB marketplace! Thanks @ColonelAdama for convincing me, I'm gonna need your help pretty soon!!
My JB+ will be for sale once I get the JB4 in hand and installed.
Here's some polished tip action that I recently added. I purchased this system originally with the black tips, the polished tips I ordered directly through Dinan and they're lightly longer.
