Just a few I've did in the last few weeks and they ALL had issues before they were completed, I lost money on every one of them!!! Everyone thinks the tuning/performance thing is great until the real crazy problems start! It's ***NOT*** the ***CUSTOMERS FAULT*** sometimes it just doesn't go right.
First, is Tom Johnson's '05 GT, he had a Howard's performance cam and new timing set installed and I did a custom tune for it; it started going into limp mode at 70 mph & after bringing it to me and diagnosing it, I found out I was given the wrong information on the rear gear set (which is imperative,especially on automatics cars which this one was) Always VERIFY what you have, not assuming or even relying on the previous owner telling you what it is and once the correct gear set was input into the tune, problem solved.
Next was David Hirt's '98 Cobra, did a complete differential overhaul with new Ford Performance gears, bearings,axles, fl**ge, rebuilt 8.8 L*D he bought from me after I went through it and made sure all was good in it, even put a new breather in it! Upon driving it heard a strange rumbling noise, after tearing it COMPLETELY apart again ( including disassembling the both mine AND his original L*D unit's and remeasuring the clutch shims) reassembled it all only to conclude it was tire noise!!! To add insult to injury, I forgot to replace the rt rear ABS unit correctly the second time and damaged it to the point it will need to be replaced, 15 hrs of labor. charged him for 7! I nearly always try to drive the vehicle before starting on them to make note of things like this, this time I didn't and paid the price for it!
Last is Greg Taylor's 2010 GT NASA Street Iron series car, these cars weight is based off torque which is dyno'd at each & every track they go to, the goal is to make as much horsepower as possible while making as little torque, quite different than anything I've ever did which is make the most of BOTH. I started on the right path but overthought it and went down the wrong "rabbit hole", thankfully Justin Gaddell and Logan Cross, owners of RPG where we dyno'd at got me back on track with some good advice and we got it, The dyno sheet shows how we started out and where we finished, lost 2-3 hp but killed the torque from 333 ft lbs down to 311 which saved him near 300 lbs in weight to have to haul around!!
