3. RC 440cc injectors
4. Blitz SBC-Id boost controller

My ECU was "unflashed" by Technosquare just so Sharif could work from a known set of maps.

I opted to do all this because my car was running very rich and generating too much boost. I wasn't willing to do the coast-to-coast ECU tuning thing with TS, who wouldn't touch the ECU (rightfully so) unless I could produce an AFR graph that displayed the whole curve (the dynos all seem to bottom out at 10.0:1 and a significant portion of my curve was sub-10).

Anyway...last dyno prior to this was 366.3/318. That was with too much fuel and too much boost (11 PSI to be exact). See The dyno graph for the details.

After having the aforementioned parts installed and tuned, the new numbers are 394.6/385. The AFR is in the low/mid 11's, the boost is right around 9 (working on some creep, but.....) and the car feels GREAT!

Here's the new graphs:



Thanks Sharif!

You can have straight PIMPNESS

I usually advise people to wait, and save up for the complete upgrade. Return fuel system, 440cc injectors, and EU items (Or the UTEC when it's released).

Sooner or later I'll get around to it, but I think I'm going to hold off until some of the soon to be released (or announced) alternatives become available. I'll definitely be letting CPR know once I'm ready.

Thanks!

But for those of us that were having problems (running to rich, bogging, really less power than the average), it is a great upgrade that you can continue to upgrade from.

Think about it, clearly it is better for the PSI we are at considering the WHP and smoothness (only needing to be in the 9psi area to make almost or at 400 WHP).

I should be around 370whp with my current setup, and am close to 11.5 afr. I guess I'm lucky that I didn't have as many problems as some (after I took the headers out, that is).

Still impressive numbers from everyone who's upgraded. And like you say, horsepower is great, but having a car that runs well and you feel comfortably safe with, is priceless.

Congrats Kelly, I will be up there soon also! Great to hear that your car is running perfect!!! I have decided to go with the U-Tech so things might be different now... Hopefully better!
