My Experience with Jnaut and HP Logic

travisjb

Just read through all this... constructive thread and I agree with the conclusions regarding J SPEC AUTOMOTIVE. I'm not going to slam the guy, because as was stated he went through a rough patch with personal issues recently, but I do not recommend his shop at this point. I will say that there was definitely a comedy of errors on my car that cost me and others involved a chunk of change. Root cause = even professionals need to follow instructions! I've detailed this a bit on my journal, will update it further as I have more to share.

I have no input on HP Logic. Haven't worked with them.

My car is being reworked at Z Fever. I have confidence in their shop... it is not a visually impressive shop but the guys that work there are solid. The owner Doug is a busy guy but always takes / returns my calls promptly. They had the difficult initial task of figuring out what the last shop did wrong... Then tearing down the ruined engine. Installing new engine, piecing it all back together and tuning. I've challenged them to tune to no more than 385whp cold... the preliminary tune looks mediocre because they were trying to detune to my target with the smaller pulley... they will swap to larger pulley tomorrow and I should have a final dyno plot to share this week.

As I've mentioned elsewhere... Z Fever is also developing a solution for our fuel starvation... it's going to be a winner of a product!
