ive been thinking of getting the Jesse tune once you buy it does he just ask for your parts or do you actually need to go log dataI am a 21 supra owner with a lock ECU. And I'm currently using JB4 was using OTS map and blown my turbo. Not pointing out who's recommendation or what leading to blown turbo.
But now I am with a new turbo/jb4 and a new custom map with @DaBears . I would like to have all the JB4 users in here to share their experiences or recommendations for JB4 tuner.
Let me share with you my experience first.
I've been running jb4 since March of 2021 at the beginning I'm doing map two and then graduate to three and E30 Map four with full bolt on such as AMS intake, AMS charged pipe, FI catless downpipe and full FI cat-back system.. anyway I'm talking to BMS about wanted more horsepowers and talk to one of their tuner and after back and forth on a few map he recommended me to try map five That's when my turbo blown, I believe map five is a little bit too high for the OEM turbo since we pushing 22 PSI.
So anyway I got a replacement OEM turbo since our car is still locked on the ECU.
Luckily some of the member in here recommend me to a tuner his name is @DaBears since I have work with him my car runs much better much smoother and produce much more powers than I expected to be out of JB4. Currently I am running E-40 the car felt great and produce great power, I was thinking somewhere next week would go to do Dyno session and see what kind of horsepower am I running.
So my purpose for this post is asking all the JB4 user is please share your experiences up here so us the 21 Supra owner can share and learn from each other.
Thanks in advance.
Thanks In advance
