haha.. Funny enough, that name dates back to highschool where I had a 96 GT that looked like a Cobra so I was nicknamed Slobra... Good point on the sound impacting my perception. I really just need to put some more miles on the car for a better opinion.

I have a 21 locked ecm supra and recently installed a catless DP. I knew I was going to get the CEL which I did and I knew the gains would only be 10-15whp without tune but I wanted the additional sound and was just going to enjoy the small gain in HP while I wait on the ECM to be unlocked but...

I did the JB+. The JB4 is more expensive as it has more features and gives a better power increase. I haven't dyno'd but supposedly the JB+ adds about 30-35 whp. Definitely feels like it...

I have a 2021 and just did the JB+ and while its obviously not going to be anywhere near as good as a real tune or even JB4, I can tell you 100% for $200 it is a tremendous value. Definitely wakes up the car.

That's a great idea, appreciate that. Luckily I am in an area that has 93 so that's all I run but I will do a log just to make sure all is well.

Installed the new JB+ and no CEL!! I can 100% say I notice the increase in boost. In fact, during a WOT pull I actually blew off my AMS charge pipe clamp because apparently I did not have it tight enough. Removed the intake and got the charge pipe better positioned and properly tightened...

Any updates?

Swift states the spec r springs are a 1.2 drop front and rear. The ride is amazing. Still comfortable in comfort but sport is noticeably stiffer yet not harsh. Couldn't be happier with them...

ADV5.0 Flow Spec Series in Satin Black 19x9.5 and 19x11 Nitto 265/35r19 and 305/30r19 Car is lowered on Swift Spec R Springs

Final results and I couldn't be happier...

Gotcha. I think are situations are unrelated. Just went for a drive and the car feels fast. Burger has mailed me a new JB+ so we shall see.

Interesting, and this is with a JB+? When the code is not active, do you notice a power improvement?

Update. Working with Burger, we are pretty sure we have bad firmware. I removed the JB+ over the weekend and cleared the codes which did not return. Went for a Sunday cruise and man did the car have power. I am pretty sure the suspected bad firmware was causing a low boost scenario. We are going...

Locked 21 here... Lets say I decide to buy and install a JB4. How do I go about getting an SMS backend flash and what improvements do I get from this if my only HP mods are a cat less downpipe and intake?

Will post pictures when mounted...

Gotcha. Honestly I think it was incorrect firmware in the JB+ because I could clear the code but at every start up, it would return. Almost like the ECM was seeing something it didn't recognize with the sensor at every key cycle. They sent me a 2nd one (which may have incorrect firmware also so...

Yea and I will deal with it until they unlock the 21's but I am mostly trying to get the cel that was generated after installing the JB+ to clear.

Shout out to EPH for the epic pricing as always and also to MAD for this DP. Honestly I was not expecting this kind of quality for the price I paid (introductory price of $167). I haven't installed yet but I'll report back once I do (locked DME 21) so not expecting massive gains but still. I'm...

Update. This weekend I installed the AMS charge pipe and full MST intake. I reinstalled the original JB+ and the car started with no CEL to my surprise. Went inside to get ready to leave for a drive and when I started the car, CEL was back. I used my buddies handheld Bosch scanner and...

I see guys talking about E30. I used to run e85 in my 2019 GT 5.0 but with a specific tune. As I understand it, our stock fuel system cannot support E85 and the benefits of E85 over E30-E50 are negligible. So are yall just adding in some E85 to get the e30ish blend at the pump? Can the stock ECM...
